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.

Selank
Selank (TP-7, CAS# 129954-34-3) is a synthetic heptapeptide analogue of the endogenous immunopeptide tuftsin (TKPR), developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. The compound is characterised by binding activity at GABA-A receptors and interactions with serotonergic and neurotrophic signalling pathways. 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.

Semax
Semax (CAS# 80714-61-0) is a synthetic heptapeptide analogue derived from adrenocorticotropic hormone fragment ACTH(4-7), extended C-terminally with a Pro-Gly-Pro (PGP) tripeptide to yield the full sequence Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP). It is studied in preclinical and in vitro models investigating neuropeptide signalling, melanocortin receptor (MC4R) interactions, and neurotrophic factor pathway modulation — including BDNF and NGF expression studies in hippocampal and cortical cell preparations. 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.

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.

KPV
KPV (H-Lys-Pro-Val-OH, CAS# 34702-62-0) is a synthetic tripeptide corresponding to positions 11–13 of alpha-melanocyte-stimulating hormone (α-MSH). As the C-terminal tripeptide fragment of α-MSH, KPV is studied in preclinical research for its activity at melanocortin receptors — particularly MC1R — and for its involvement in intracellular signalling pathway models including NF-κB. 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.
