Immunomodulatory Research Peptides
This category covers peptides investigated for their role in immune signaling pathways, cytokine regulation and inflammatory cascade research. Both compounds listed here are supplied as laboratory research chemicals only and are not intended for human or veterinary use.
Thymosin Alpha-1 (Tα1) 10mg is a 28-amino-acid thymic peptide studied extensively in laboratory models of T-cell maturation, toll-like receptor signaling and dendritic cell activity, and it is one of the most widely referenced immunological research peptides in the published in-vitro literature. KPV 10mg is the C-terminal tripeptide fragment of alpha-melanocyte-stimulating hormone, investigated for its influence on NF-κB signaling and pro-inflammatory cytokine expression in cultured epithelial and immune cell lines.
Because the category is deliberately narrow, researchers often pair these two sequences with compounds from our cellular modulation and melanocortin collections when designing comparative cytokine panels. KPV in particular is studied on both sides of that boundary, since its activity is examined in immune signaling work and in melanocortin receptor research alike.
Purity and documentation
Both peptides ship from the United States and are manufactured to a minimum 99% HPLC purity specification. Batch certificates of analysis (COAs) are published on many of our product pages and typically include an HPLC chromatogram, mass-spectrometry identity confirmation and a stated peptide content, which lets a laboratory document the provenance of its materials.
Vials are supplied lyophilized, are intended for cold storage, and are reconstituted at the bench with an appropriate sterile laboratory diluent such as bacteriostatic water. Immunological research peptides are sensitive to repeated freeze-thaw cycles, so most laboratories aliquot the solution once it has been prepared.
Nothing sold in this category is a medicine. These materials have not been evaluated by any regulatory agency for safety or efficacy in people, no claim of any physiological effect is made anywhere on this site, and orders are accepted only from research professionals and institutions equipped to handle investigational compounds.

Frequently asked questions
What is the difference between KPV and Thymosin Alpha-1?
KPV is a three-amino-acid fragment of alpha-melanocyte stimulating hormone, studied in the literature for its role in inflammatory signaling. Thymosin Alpha-1 is a 28-amino-acid peptide originally characterized from thymic tissue and investigated for its interaction with innate immune receptors in preclinical models. The two differ in size, origin and the pathway they are studied in. Both are supplied as laboratory research material only.
How do I know a Thymosin Alpha-1 lot matches its label?
Every lot is supplied to a minimum 99% HPLC purity specification, and batch certificates of analysis are published on many individual product pages. A COA typically pairs a chromatogram reporting the purity percentage with mass spectrometry data confirming molecular weight against the stated sequence. Matching the lot number on the vial to the published document is a routine verification step for incoming laboratory reference material.
Why are immunomodulatory peptides supplied lyophilized rather than in solution?
Lyophilization removes water, and the literature reports that peptides held as a dry powder are considerably more stable in storage than the same sequence kept in solution. A sealed lyophilized vial tolerates shipping and cold storage with less degradation, which matters when a laboratory needs consistent reference material across a study. KPV and Thymosin Alpha-1 are therefore supplied as lyophilized powder for research use only.
Can KPV or Thymosin Alpha-1 be bought for personal use?
No. True Form Peptides supplies both as laboratory research chemicals for in vitro and preclinical scientific work only. They are not for human or veterinary use, and no dosing, reconstitution or administration guidance is provided with any order. Shipping is available within the United States only, with orders typically entering processing within one to two business days before tracking is issued to the buyer.
