Decision summary

Key benefits

Research relevance includes EPOR signaling, erythroid-progenitor biology, hypoxia pathways, glycoprotein characterization, potency assays and anti-doping analytical methods
Clinical efficacy and performance effects are not product benefits of this RUO lot.

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: 11096-26-7
Formula: C₈₀₉H₁₃₀₁N₂₂₉O₂₄₀S₅ (18235.7 g/mol) describes the ¹⁶⁵-residue polypeptide chain; mature epoetin is a glycoprotein of approximately 30 kDa, so one empirical formula does not represent its glycans. Confirm construct, expression system, glycoform and sialylation profile, content and cell-based potency for the released lot.
Molecular weight: 18235.7 g/mol
Appearance: Lot- and formulation-specific material; confirm physical form, colour and container on the released-batch COA
Purity: Multi-attribute lot release; require identity, glycan/charge profile, aggregates/fragments, content, process impurities and qualified bioactivity rather than one HPLC percentage · target, verify batch COA
Storage: Follow the released-lot COA and manufacturer stability instructions. Avoid freezing, agitation and unvalidated excursions where specified; exact requirements depend on the formulation and container.
MOQ: 1 kit (10 vials) per SKU
Lead time: Confirmed with quote

Qualification matrix

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 EPO

Erythropoietin is an endogenous glycoprotein hormone, and epoetins are recombinant erythropoiesis-stimulating biologics. Approved labels apply to specific finished medicines. An RUO EPO lot requires exact product identity, expression-system, glycoform, aggregate, potency and microbiological qualification and is subject to strict end-use and anti-doping controls.

EPOR signaling, erythropoiesis and hypoxia research, glycoprotein analytical and bioactivity method development, reference-lot qualification and anti-doping detection research
These are research applications, not clinical indications.

Mechanism context

The question the literature is testing

EPO binding activates EPOR-associated JAK2 and downstream STAT5, PI3K/Akt and MAPK signaling in erythroid progenitors. Proposed nonhematopoietic receptor mechanisms remain debated. Activity is sensitive to construct, glycosylation, sialylation, aggregates and assay design and must be measured for the released lot.

Compatibility, limitations and decision context

Not for human or veterinary use
Approved ESAs carry serious boxed warnings, including thromboembolic, cardiovascular, mortality, tumor-progression and antibody-mediated PRCA risks in defined clinical contexts
EPO is prohibited at all times under WADA S2.1.1
Follow the SDS, institutional biologics controls and end-use restrictions.

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.

Independent test fails? Full refund.

Representative records, refreshed periodically

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.

Ask for the current packet, not a generic certificate

Require exact molecular product and expression system, peptide mapping or sequence confirmation, intact/subunit mass as appropriate, glycan and sialylation profile, charge variants, SEC aggregates/fragments, content, cell-based potency, endotoxin, host-cell proteins/DNA where relevant and storage history

Handling

Plan storage before the parcel arrives

Follow the released-lot COA and manufacturer stability instructions. Avoid freezing, agitation and unvalidated excursions where specified; exact requirements depend on the formulation and container.

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.

Product FAQ

Questions buyers ask about EPO

Why can EPO not be qualified by CAS and HPLC purity alone?+

Epoetin is a glycoprotein biologic. Expression system, amino-acid construct, glycan and sialylation distribution, charge variants, aggregates, fragments and cell-based potency all affect identity and behavior. Procurement therefore requires orthogonal structural, glycan, purity and bioactivity data for the released lot.

Are epoetin alfa, darbepoetin and CERA interchangeable?+

No. They are related erythropoiesis-stimulating agents but differ in sequence, glycosylation or conjugation and pharmacological properties. Each must be identified and characterized as its exact molecular product; class-level literature does not establish lot equivalence.
