    Who We Are

    About Prime Science Supply

    Prime Science Supply is a United States supplier of research-grade synthetic peptides and bioactive compounds, offered under the Prime Bio Labs brand. Every item in the catalog is supplied to an HPLC-UV purity specification of 98% or higher. Certificate of Analysis availability and level of detail vary by product and by lot. Supplied for laboratory research use only.

    Our Mission

    Research is only as reliable as the material it is performed on. An assay cannot tell you whether an unexpected result came from the compound named on the label or from a truncated sequence, a residual reagent, or a counter-ion nobody accounted for. Prime Science Supply exists to remove that ambiguity before the material ever reaches the bench.

    We are a new company, and we would rather be measured by the standard we hold than by adjectives. That standard is written out in full below, so it can be checked against what actually arrives in the box.

    Why per-batch documentation matters

    Peptide synthesis is a batch process. Two lots of the same sequence, produced by the same route, can differ in impurity profile, residual content, and net peptide mass. A document that describes a product in general therefore says very little about one specific vial in one specific freezer. Only documentation tied to a lot number does. That is why lot-level analytical paperwork is part of the material rather than a marketing attachment. Availability of that documentation varies by product and by lot.

    What HPLC-UV measures

    High-Performance Liquid Chromatography separates the components of a sample by how strongly each one interacts with a stationary phase as a solvent gradient carries it through the column, while an ultraviolet detector records each component as it elutes. For a synthetic peptide, that separation resolves the target sequence from deletion and truncation products and other synthesis-related impurities. Purity is reported as the area of the target peak relative to the total integrated peak area. Our specification is 98% or higher for the compound as supplied, and it is applied the same way across the catalog. Where a Certificate of Analysis is issued for a lot, that is where the lot's measured result is reported.

    What a Certificate of Analysis proves

    A Certificate of Analysis is a record, not a promise. A certificate identifies the product, the batch it belongs to, the analytical method applied, and the result that method returned. Read alongside the lot number on the vial, it lets a researcher connect a specific observation to a specific, documented batch of material. What no certificate can establish is fitness for any human or veterinary purpose, and a supplier who implies otherwise is describing something other than analytical chemistry.

    What batch traceability means

    Traceability means the lot number is load-bearing: a batch that is received, recorded against its own analytical documentation, and kept as a distinct unit through storage and fulfillment lets the vial in hand be tied to the documentation held for it. That is what makes a question about a batch answerable instead of hypothetical. This is the standard we are building toward; today the documentation we publish is per catalog reference, and availability varies by product and by lot.

    Catalog and handling

    The catalog is deliberately curated rather than exhaustive: it lists compounds that can be supplied to this standard consistently, and it grows as the documentation supports it. Material is supplied sealed in its original container and dispatched in protective outer packaging. Every order ships domestically within the United States with tracking. We do not offer cold-chain or temperature-controlled transport.

    Research use only, without exception

    Everything supplied by Prime Science Supply is intended for laboratory research use only. These materials are not drugs, dietary supplements, cosmetics, or medical devices. They are not for human or veterinary use, not for diagnostic procedures, and not for any clinical application. We do not provide preparation, administration, or dosing guidance of any kind, and we will not discuss it. That boundary is not a disclaimer at the bottom of a page — it is how this company operates. Purchasers are responsible for handling these compounds in a qualified research setting, by trained personnel, and in accordance with all applicable federal, state, and local law.
