Thymalin

Thymalin (Catalog THYMALIN, CAS 63958-90-7) is supplied as a laboratory research reference material intended strictly for in-vitro and laboratory research use. It is a synthetic thymic polypeptide complex presented as a white to off-white lyophilized powder, defined by a fraction molecular weight range of approximately 1000-10000 g/mol rather than by a single discrete mass. This range reflects the polypeptide-mixture nature of the material and is a characterization parameter analysts should account for when developing chromatographic or mass-spectrometric methods.

As a peptide fraction, Thymalin is not resolved as a single sharp peak in the manner of a monomeric peptide standard; rather, HPLC characterization yields a defined profile against which lot-to-lot consistency is assessed. Purity is specified at not less than 98% by HPLC, with lot-specific identity, profile, and purity data documented on the accompanying Certificate of Analysis, available on request. Investigators working with Thymalin as a reference item typically evaluate it using reversed-phase HPLC with UV detection at peptide-bond absorbance wavelengths, size-exclusion chromatography to confirm the fraction molecular weight window, and ancillary techniques such as Kjeldahl or Lowry-type nitrogen/protein assays for mass balance.

The lyophilized format supports extended dry storage stability and clean reconstitution in laboratory aqueous systems for analytical workflows. Formulators and method-development chemists should treat Thymalin as a polydisperse polypeptide reference and select solvents, filtration steps, and column chemistries appropriate to a mixed-peptide analyte rather than to a defined small peptide.

Published scientific literature has examined Thymalin in preclinical research contexts, and this listing exists to support qualified laboratories referencing that body of work under controlled in-vitro conditions. PEPTIDE.Power makes no therapeutic, diagnostic, or efficacy claims regarding Thymalin and provides no administration or dosing guidance of any kind.

This material is not a drug, dietary supplement, cosmetic, or food. It is not intended or authorized for human or veterinary use, injection, ingestion, topical application, or any form of in-vivo administration, and must be handled exclusively by trained personnel within an appropriate laboratory setting.

Supplied as a lyophilized (freeze-dried) powder in a sealed vial. A research reference material - not a finished product and not a delivery device. Net contents per unit are shown in the product options.

Store the sealed lyophilized powder at -20 C, protected from light and moisture. After reconstitution for laboratory use, keep cold and use promptly. Handle per standard laboratory practice; a Safety Data Sheet (SDS) is available on request.
