Description
Lymphotactin is the only known member of the C chemokine family, and signals through the receptor XCR1, formally known as GPR5. The spleen shows the highest level of lymphotactin compared to peripheral leukocytes, lung, colon and small intestine. Lymphotactin is chemotactic towards lymphocytes, but not towards monocytes or neutrophils. Recombinant Human Lymphotactin is a 10.0 kDa protein consisting of 92 amino acid residues.

Biological Activity
Determined by its ability to chemoattract human T cells using a concentration of 10.0–100.0 ng/ml.
Endotoxin
Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).
Reconstitution
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1–1.0 mg/ml. Do not vortex. This solution can be stored at 2–8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at –20°C to –80°C.
Storage/Expiration
