Immune Signalling Stack

Thymosin α1, KPV and ARA-290 for cytokine, T-cell and innate-receptor assays.

Two Thymosin Alpha-1 vials, two KPV vials and ARA-290 for cytokine-release assays, T-cell maturation models and innate-repair-receptor signalling studies.

Why these compounds are studied together

Thymosin α1 is a 28-amino-acid thymic peptide studied for TLR signalling and T-cell maturation.
KPV, the α-MSH C-terminal tripeptide, is studied for NF-κB inhibition in epithelial and immune cells.
ARA-290 is an EPO-derived peptide that targets the innate repair receptor without EPO-receptor erythropoietic signalling.

Bench handling notes

Use endotoxin-tested reagents throughout: immune-cell assays are highly sensitive to LPS contamination.
Include an LPS-only positive control and a vehicle control in each plate.

Laboratory handling only. See the research blog for storage, reconstitution and COA guides.
