Merck, SRP3304-25UG, INSL5/INSL7 HYBRID human

Biochem/physiol Actions
The Insulin/Relaxin structural family of proteins consists of at least seven members, each containing an Insulin-like hetero-dimeric structure consisting of two polypeptide chains held together by two inter-chain disulfide bonds. INSL7-INSL5 hybrid contains the B-chain of INSL7 (Relaxin-3), linked to the A-chain of INSL5. The INSL7-INSL5 hybrid protein can specifically activate the G protein coupled receptors, GPCR135 and GPCR142, but unlike Relaxin-3, does not induce significant activation of the LGR7 receptor. Recombinant INSL7-INSL5 hybrid is a hetero-dimeric 5.7 kDa protein consisting of a 27 amino acid B-chain disulfide linked to a 21 amino acid A-chain.
Physical form
Lyophilized with no additives.
Preparation Note
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
