ZELLKRAFT LABS

WHAT ARE PEPTIDES?

Short amino-acid chains, documented for the bench
Peptides are short chains of amino acids — the building blocks of proteins — widely used as reference compounds in laboratory research. At ZellKraft Labs, every peptide is supplied exclusively for in-vitro research, documented with a per-batch certificate of analysis, and described in neutral, factual terms. No claims — just paperwork you can verify.
  • Documented purity, assayed by HPLC
  • A certificate of analysis with every batch
  • Supplied for in-vitro laboratory research only

The standard

Built on documentation, not claims

Four things every compound clears before it reaches your bench.

Documented purity

Every batch is assayed by HPLC and published at ≥ 98% purity — a figure you can verify, not a promise.

A certificate per batch

HPLC results, mass-spec identity, and the test date travel with every batch, downloadable as a PDF.

EU logistics

Handled as laboratory material and dispatched tracked via DHL Express across the European Union.

Research-use integrity

One posture everywhere — in-vitro laboratory research only, with no human or veterinary use.

Certificate of analysis

Every batch, documented

Open any compound and you find the same thing: an HPLC purity assay, mass-spec identity confirmation, the batch number, and the date it was tested. We publish what we measure — the certificate is part of the product.
