Every document, without asking.
Datasheets, representative certificates and safety data sheets for all 42 products. Lot-specific COAs ship with the order; anything that needs a signature is marked as such.
Representative COAs illustrate the test panel; the released certificate for your lot ships with the order. Files open in a new tab.
Notes from R&D and regulatory.
Short, specific and written by the people who ran the experiment.
RegulatoryWhat an FDA DMF actually buys you when you licence a CGT raw material
A Type II DMF is not an approval — it is a closed reference. Here is how sponsors use DMF 038124 during an IND review, and what the auditor will ask for next.

ProtocolFeeder-free NK expansion from cryopreserved CBMC: a 14-day protocol
A step-by-step protocol using AMMS® NK Cell Culture Kit 3.0, including seeding density, feeding cadence and the purity you should expect at day 14.
Read the noteThe questions that come up first.
Yes. The majority of the bead, antibody and cytokine portfolio is available in GMP grade manufactured under ISO 13485 and ISO 9001 quality systems, with batch-specific documentation. RUO-grade equivalents are available for earlier research stages so that you can qualify the same reagent early.
Two Type II Drug Master Files are on record: DMF 038124 for the ActSep® CD3/CD28 separation and activation beads, and DMF 038820 for the anti-human CD28 monoclonal antibody. A DMF allows a sponsor to reference our manufacturing information without receiving it directly. Letter of authorisation requests are handled by our regulatory team.
We have supported audit data packages for more than 30 customers, and our quality team routinely hosts on-site and remote audits of the 3,200 m² R&D and GMP facility. Contact us to schedule an audit or request the standard audit package.
Enter the lot number in the COA lookup on our Resources page. If the certificate is not yet indexed, email info@tlbiotechnology.com with the lot number and product name and we will send it within one business day.
Yes. Orders ship from our US distribution point in Carlsbad, California and from our manufacturing site, with cold-chain packaging validated for the destination. Lead times depend on grade and pack size; quote requests include an estimated ship date.
Yes. Evaluation samples are available for most catalogue items at RUO grade, and we can discuss a qualification package for GMP-grade material under a technical agreement.
