Lot history for this item

About this material

What it is

A fifteen-residue peptide and a seven-residue thymosin β4 fragment, co-lyophilised into a single vial under nitrogen at a 15 mg total fill. Because the components are released before they are blended, the certificate carries a per-component purity figure and both component lot references stay searchable in the archive under their own numbers. A prior lot of this item failed incoming inspection and its certificate is still published, marked as held, with the reason written out.

Laboratory handling

Storage and material handling

  1. 01Equilibrate the sealed vial to ambient temperature before breaking the seal.
  2. 02Both components are released separately before the blend is filled. The blend certificate reports each component figure rather than one averaged number, because an average cannot be traced back to a component lot.
  3. 03Cake integrity is part of the release specification — photograph the cake on receipt if your protocol requires an incoming-inspection record.
  4. 04An earlier lot of this item (VL-24204-A) was quarantined at incoming inspection and never sold. The held certificate is published in the archive.
  5. 05Aliquot stocks for single use and log each freeze-thaw cycle against the lot.
  6. 06Dispose of unused material and rinsate according to your institution's chemical waste procedure.

Laboratory storage and material handling only. No dose, concentration, route, frequency or administration guidance is provided for this or any other item, for humans or animals. Where an item is offered in more than one option, the option is a quantity of material, not a dose.

Documentation

They publish their held lots

I went looking for the quarantined lot after a colleague mentioned it and found the full certificate still in the archive, marked as held, with the reason written out. Publishing a failure is the only part of a quality claim that costs anything, so it is the only part I read as evidence.

Documentation

Blend components stayed individually traceable

The certificate reports each component figure separately instead of collapsing the blend into one averaged number. That distinction matters when an auditor asks which component lot went into which experiment, and most suppliers get it wrong.

Shipping

Customs paperwork was correct the first time

Research-use declaration and the commercial invoice both matched what our import broker needed. Cleared in a day and a half. The previous supplier we used cost us three weeks and a re-order because of one wrong line on a form.
