02How They Differ
Thymosin Alpha-1
A thymic peptide studied for T-cell maturation and Toll-like-receptor signaling.
Thymosin Alpha-1 is a 28-amino-acid N-terminally acetylated peptide derived from the thymic protein prothymosin alpha. Research focuses on its role in T-cell maturation and differentiation and modulation of Toll-like receptors (TLR2, TLR9) on dendritic cells.
DSIP
A nonapeptide studied for delta-wave sleep architecture and circadian signaling.
DSIP (delta sleep-inducing peptide) is a naturally occurring nonapeptide first isolated for its association with delta-wave EEG activity. Research models study its role in sleep architecture and circadian regulation.

03Selecting for a Research Model
Thymosin Alpha-1 (Immune) and DSIP (Cognitive) occupy different research categories, so the choice usually follows the pathway under study. Selection depends on the research question, model system, and endpoints. Both are supplied strictly for laboratory research and are not for human or veterinary use.
Whichever you select, every Ethos Bio lot is verified the same way — a five-point independent panel with a batch-specific Certificate of Analysis. See how we test →
