TECK Recombinant Protein | catalog# 40-397
Background
TECK is a CC chemokine, specifically expressed by thymic stromal cells, and signals through the CCR9 receptor. TECK is chemotactic towards activated macrophages, thymocytes and dendritic cells. Recombinant human TECK is a 14.2 kDa protein containing 127 amino acid residues, including the four conserved cysteine residues present in CC chemokines.

E. coliReactivity
n/aTested Application
n/aStorage
The lyophilized TECK recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted TECK is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing TECK recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.Species Reactivity
