Background CD8 is a dimeric complex made up of two Ig superfamily members (1). The CD8 alpha chain is a type I transmembrane glycoprotein that can dimerize either with itself forming CD8 alpha alpha, or with a 30-35 kDa CD8 beta chain, forming CD8 alpha beta (2). CD8 alpha contains one V-type Ig-like domain in its extracellular region that binds to class I MHC molecules. CD8 alpha beta is a TCR co-receptor, while CD8 alpha alpha promotes T cell survival and differentiation (1, 3). The mature cotton rat CD8 alpha consists of a 159 amino acid (aa) extracellular domain (ECD), and runs at ~30 kDa under reduced condition. Within the ECD, cotton rat CD8 alpha shares 49%, 47%, and 54% amino acid sequence identity with human, mouse, and rat CD8 alpha, respectively.
Lyophilized from 10mM PBS, 5% Trehalose, 5% Mannitol, pH7.4.
