Scientific name
L-Threonyl-L-lysyl-L-prolyl-L-arginyl-L-prolyl-glycyl-L-proline (Selank; TP-7)
Amino acids
7
Sequence
TKPRPGP
Molecular weight
751.9 g/mol
Formula
C33H57N11O9
CAS
129954-34-3
Origin
Synthetic analog of the endogenous tetrapeptide tuftsin (Thr-Lys-Pro-Arg, a fragment of the human immunoglobulin G heavy chain), elongated at the C-terminus with Pro-Gly-Pro.
Storage requirements
Lyophilized (powder)
-20°C · stable long-term; protect from light and moisture
Reconstituted
2-8°C · use within 30 days; avoid repeated freeze-thaw cycles
Room temperature
Lyophilized powder tolerates short shipping excursions, but ambient storage accelerates hydrolysis and aggregation; reconstituted solution should not be held at room temperature beyond a few hours
