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.
Human CCL25 expressed in E.coli
CAT# CSC-CTK0594-20 (20 μg); CAT# CSC-CTK0594-100 (100 μg)
Greater than 98% as determined by SDS-PAGE and HPLC analysis.
Determined by its ability to chemoattract human monocytes using a concentration range of 1.0- 10.0 ng/ml.
Less than 1 EU/μg.
Lyophilized from a sterile-filtered solution with no additives.
Please centrifuge product briefly before opening the vial. Reconstitute in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized powder, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted TECK should be used immediately or stored in undiluted working aliquots at -20°C. Avoid repeated freeze / thaw cycles.
