Description: Peptide to Apamin Form: Lyophilized powder CAS Number : 24345-16-2Molecular Formula : C79H131N31O24S4Molecular Weight : 2027.37Purity : > 95%Chemical Structure : H-Cys-Asn-Cys-Lys-Ala-Pro-Glu-Thr-Ala-Leu-Cys-Ala-Arg-Arg-Cys-Gln-Gln-His-NH2 (Disulfide bridge Cys1-Cys11, Cys3-Cys15)Application : Apamin, which has been isolated from bee venom, is the smallest neurotoxic polypeptide known. It is the only polypeptide neurotoxin that passes the blood-brain barrier. It has several features in common with the snake and scorpion neurotoxins: like these, apamin is a low-molecular-weight basic peptide, and the molecule is crosslinked by disulfide bridges.Storage/Stability : Shipped at 4°C. Store at -20°C for one year.
