what each one is
KPV
Tripeptide alpha-MSH fragment
KPV is a tripeptide composed of lysine, valine, and proline, corresponding to the C-terminal fragment (residues 11–13) of alpha-melanocyte-stimulating hormone (alpha-MSH). It is the smallest sequence retained from that parent peptide and is widely used as a compact reference compound in cellular signaling research, where its short chain length makes it convenient for controlled in-vitro work.

Thymosin β4 fragment · tissue-repair research
TB-500 is a synthetic 43-amino-acid peptide corresponding to an active fragment of thymosin beta-4, a naturally-occurring actin-binding protein. Verve supplies it as a high-purity research compound for tissue-repair and cellular research.

What is KPV?
KPV is a tripeptide (lysine-valine-proline) corresponding to the C-terminal fragment of alpha-MSH. Verve supplies it as a research compound for laboratory use only, not for human or veterinary use.
What is KPV studied for in research?
In in-vitro and pre-clinical models it is used as a reference compound in inflammatory-signaling, cytokine-expression, and melanocortin-pathway research. Verve makes no claims about use in humans or animals.
What is TB-500?
TB-500 is a synthetic 43-amino-acid peptide based on an active fragment of thymosin beta-4. Verve supplies it as a research compound for laboratory use only.
What is TB-500 studied for in research?
It is used in cell-migration, actin-regulation, angiogenesis, and tissue-repair research models. It is not for human or veterinary use.
