SS-31
SS-31 (Elamipretide; MTP-131) is a synthetic cell-permeable tetrapeptide developed by Hazel Szeto and Peter Schiller, featuring an alternating aromatic–cationic residue pattern — D-Arg-Dmt-Lys-Phe-NH₂ — where Dmt denotes 2′,6′-dimethyltyrosine. This motif enables selective accumulation at the inner mitochondrial membrane through electrostatic and hydrophobic interactions with cardiolipin (CL), an anionic phospholipid essential to electron transport chain organisation. SS-31 is a widely used tool compound in mitochondrial biology research for investigating cristae architecture, respiratory complex dynamics, and reactive oxygen species production.

NAD+
NAD⁺ (Nicotinamide Adenine Dinucleotide, CAS# 53-84-9) is a naturally occurring dinucleotide coenzyme found in all living cells, functioning as an essential redox cofactor in cellular energy metabolism. It participates as an electron carrier in key metabolic pathways and serves as a substrate for enzymes including sirtuins (SIRTs) and poly(ADP-ribose) polymerases (PARPs). Supplied by BIOSTACKS as a lyophilized powder for in vitro laboratory research use.

Epitalon
Epitalon (CAS# 307297-39-8) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly (AEDG), developed as a research analogue of Epithalamin — a polypeptide extract isolated from the bovine pineal gland. It is studied in cell biology models examining telomerase activity, TERT (telomeric reverse transcriptase) gene expression, cell cycle regulation, and neuroendocrine signalling pathways associated with the pineal gland. As the shortest characterised peptide with documented telomere-related activity in preclinical models, Epitalon occupies a unique position in the in vitro research literature on replicative senescence and chromosomal stability. Supplied by BIOSTACKS as a lyophilized powder for in vitro laboratory research use. This compound has not been authorized by Health Canada for any therapeutic, clinical, or human use.

Thymosin Alpha 1
Thymosin Alpha-1 (Tα1; Thymalfasin) is a 28-residue N-terminally acetylated polypeptide originally isolated from bovine thymus fraction 5 by Goldstein and Low in 1977. As the primary biologically active component of thymosin fraction 5, it is among the most studied immunomodulatory peptides in preclinical research, with proposed actions at Toll-like receptors (TLR2, TLR9) and downstream NF-κB/cytokine signalling pathways. Its sequence is fully conserved across human, mouse, rat, and bovine species, making it an important tool compound in cross-species immunological research models.
