VIP, or vasoactive intestinal peptide, is a neuropeptide of 28 amino acid residues that belongs to a glucagon/secretin superfamily, and it exerts its actions through three G-protein-coupled receptors (PAC1, VPAC1, and VPAC2). VIP is synthesized by trophoblast cells; it regulates trophoblast cell function and interaction with the major immune cell populations present in the pregnant uterus.

复溶方法 | A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information. |
存储 |
It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted protein solutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
运输方式 |
In general, Lyophilized powders are shipping with blue ice. |
