分子量
The recombinant canine XCL1 comprises 98 amino acids and has a predicted molecular mass of 11.3 kDa. The apparent molecular mass of the protein is approximately 18-23 kDa in SDS-PAGE under reducing conditions due to glycosylation.
バッファー
Lyophilized from sterile 20mM Tris, 500mM NaCl, 10% glycerol, pH 7.4.
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.
Please refer to the specific buffer information in the hard copy of CoA.
配送
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

Lymphotactin / XCL1 背景情報

This antimicrobial gene encodes a member of the chemokine superfamily. Chemokines function in inflammatory and immunological responses, inducing leukocyte migration and activation. The encoded protein is a member of the C-chemokine subfamily, retaining only two of four cysteines conserved in other chemokines, and is thought to be specifically chemotactic for T cells. This gene and a closely related family member are located on the long arm of chromosome 1.
完全な名称
chemokine (C motif) ligand 1
