Decision summary
Key benefits
A defined PubChem reference structure is available for KEDP identity comparison.
The page separates reference-name evidence from batch-level composition claims.
Review the matching batch COA first; scope additional sequence or supplied-form evidence only when the buyer's written procedure requires it.
Published research context is presented for literature orientation only. It is not a dosing, treatment or human-use instruction.
Qualification data
Specifications to confirm against the released lot
CAS

Formula
C20H33N5O9
Molecular weight
487.5 g/mol
Appearance
White to off-white lyophilized material; confirm composition and lot appearance on the batch COA
Purity
Lot-specific release specification; do not assign KEDP purity until the batch identity, supplied form, chromatographic purity and quantitative peptide content are confirmed · target, verify batch COA
Storage
Follow the released-lot COA, SDS and validated stability data for the confirmed chemical entity, supplied form, container and intended assay. A trade name alone cannot establish temperature, light protection, freeze-thaw tolerance or solution hold time.
Identity, purity and content are separate release questions.
Identity
Confirm the stated molecule and supplied form. Start with the matching batch COA; request sequence-level evidence only when the buyer's written procedure requires it and availability or a separate scope has been agreed.
Purity
Review RP-HPLC method conditions, wavelength, integration and related-peak handling. A percentage without the method is not enough.
Content
Net peptide content is not the same as gross lyophilized powder weight. Ask which assay supports the stated amount and whether water/counter-ion is addressed.
Stability
Follow the storage condition stated on the batch COA or label from receipt onward.
Research context
What researchers study about Prostamax
PubChem maps the reference name Prostamax to the KEDP tetrapeptide (Lys-Glu-Asp-Pro), CID 9848296. Because trade-name preparations may not be compositionally equivalent, buyers should treat the PubChem record as a reference identity and confirm that the offered lot actually matches KEDP by its COA and identity data.
KEDP short-peptide identity and sequence research
Chromatin and gene-expression model research reported in the limited literature
Mechanism context
The question the literature is testing
A small, older literature base discusses KEDP and related short peptides in chromatin and gene-expression models. This evidence does not establish clinical efficacy, tissue selectivity or equivalence between every product sold under the Prostamax trade name.

Dose / exposure contextProtocol-specific; verify the cited primary source
Routes and exposure contexts summarize cited studies or approved finished-product labels. They are not instructions for administering this RUO material; no customer dose is provided.
Evidence boundaries
Compatibility, limitations and decision context
No robust human safety dataset or validated clinical-use framework was identified.
Do not assume a trade-name preparation is chemically identical to KEDP without lot-specific analytical confirmation.
Interactions reported in the literature
No reliable combination or compatibility data were identified for a generic trade-name preparation.
Literature context is not a supplier release result or human-use instruction. Follow your institution's approved laboratory risk assessment.
Batch documentation
Prostamax batch COAs
Laboratory: Manufacturer's QC laboratoryTests: HPLC purity · MS identity · endotoxin · fill amount
No batch COA is published for this product yet. Ask sales for the latest available document.
Previews are blurred on purpose so the documents cannot be reused; third-party reports show their first page only. Sales sends the clear full version for the product and strength you ask about.
Published COAs show recent representative batches and may not be the newest. For a quote or shipment, sales confirms the lot and sends its COA.
Third-party reports, added progressively
Previews of the first page of third-party reports are on our Quality page and on the matching product pages; sales sends the full report on request. You can also send any vial from your order to an independent laboratory of your choice. Unless agreed otherwise in writing, the buyer pays for optional testing.
Help reviewing your COA
Need help reading a batch COA or third-party report? Sales can explain the test items, specifications and how the results relate to the lot under discussion.
On every batch COA: HPLC purity · MS identity · endotoxin · fill amount · Verify LyoPep
Ask for the current packet, not a generic certificate
The COA should state whether the material is defined KEDP or a multi-component preparation and identify the supplied form.
For a KEDP claim, reconcile sequence, formula, molecular weight, intact mass, chromatographic purity, quantitative peptide content, counterion, water and residual solvents with PubChem CID 9848296 and lot data.
Bioburden, endotoxin and sterility are separate attributes and cannot be inferred from identity or HPLC area purity.

Handling
Plan storage before the parcel arrives
Follow the released-lot COA, SDS and validated stability data for the confirmed chemical entity, supplied form, container and intended assay. A trade name alone cannot establish temperature, light protection, freeze-thaw tolerance or solution hold time.
State the destination and timing so receipt can be planned, then move the material into its stated storage condition on arrival.
Buyer FAQ
Terms to settle before the purchase order
Can a buyer arrange third-party testing?+
Yes. You can send any vial from your order to an independent laboratory of your choice. If you want the laboratory, specification, sampling, method and acceptance rule agreed with us before testing, sales confirms them in writing. Unless otherwise agreed in writing, the buyer pays the cost of this optional testing.
What if my own lab test shows the product is out of specification?+
Send any vial from your order to an independent laboratory of your choice. If the report shows the product does not meet the specification on its COA — purity below the stated minimum, or an identity that does not match — share the report with our sales team and we refund that product in full.
Does HPLC purity prove peptide content?+
No. Chromatographic purity describes the relative peak profile under a stated method. Identity, water, counter-ion, residual solvents and assay/content may require separate methods.
How should material be stored after delivery?+
Move it into the storage condition stated on the batch COA or label as soon as it arrives, and record the package condition on receipt.
How are payment terms handled?+
Available methods and milestones depend on order value, destination and project type. The pro forma invoice should state currency, bank details, fees, payment milestones and the release condition.
Why must the testing laboratory understand peptide chemistry?+
Free-base and salt forms, hydrophilic and hydrophobic sequences, aggregation and adsorption can change sample preparation and method suitability. Use a laboratory experienced with the molecule class.
These are buyer-qualification references, not claims that this RUO material is regulated, certified or released under those frameworks. Applicability depends on the buyer's workflow and jurisdiction.

Short-peptide chromatin research associated with the Prostamax/KEDP literature
Georgian Medical News / PubMed · 2012 · peer-reviewed cell-model research; limited direct product evidence
Does the name Prostamax prove that the supplied lot is KEDP?+
No. PubChem CID 9848296 maps the name Prostamax to the KEDP tetrapeptide H-Lys-Glu-Asp-Pro-OH, formula C₂₀H₃₃N₅O₉ and molecular weight 487.5 g/mol. That database reference is useful for comparison, but a trade name alone does not establish an offered lot's sequence, salt, purity or equivalence. The quote and COA must explicitly identify the supplied material, supported by orthogonal identity data.
What does the published Prostamax or KEDP evidence establish?+
The independently located literature is small and includes an older PubMed-indexed cell-model paper on short peptides and chromatin decondensation. It does not establish clinical efficacy, prostate selectivity, an approved indication or equivalence among all trade-name preparations. Treat vendor summaries and unindexed citations as leads to verify, not as released-lot evidence.
Which documents should be requested for first-lot qualification?+
Ask sales for the batch COA matched to the offered lot and confirm whether the material is defined KEDP or a multi-component preparation. Review the supplied form, methods, specifications and results recorded there. Any additional sequence evidence, raw chromatogram, quantitative content, water, residual solvents, bioburden, endotoxin or sterility required by the buyer's written procedure must be agreed separately before quotation.
