Speract TFA is a sea urchin egg peptide that regulates sperm motility, also stimulates sperm mitochondrial metabolism.The stimulation of sperm with speract depolarizes the mitochondrion and increases the levels of NADH.?Surprisingly, these responses are independent of external Ca(2+) and are due to the increase in intracellular pH (pHi) induced by speract.?

Bintrafusp alfa (M7824) is a bifunctional fusion protein consisting of the extracellular structural domain of TGF-βRII (a TGF-β “trap”) fused to a monoclonal antibody against human immunoglobulin G1 fused to programmed death ligand 1 (PD-L1).

β-CGRP, human ,a 37-amino acid peptide,is the beta form of Calcitonin-gene-related peptide (β-CGRP), involved extensively in regulation of the cardiovascular and nervous systems. β-CGRP contains a disulphide bridge at the N-terminus, a C-terminal phenylalanine amide important for immune recognition, and an a-helix between residues 8 and 18.
