Recombinant Mouse CCL25 (TECK) (carrier-free)

CCL25, which signals through CCR9 receptor, is mainly expressed in the thymus and small intestine. In the thymus, CCL25 contributes to correct thymocyte maturation by promoting CD4+CD8+ thymocyte trafficking through the cortex via alpha4beta1-dependent adhesion to VCAM-1, and also stimulates CD4+CD8- cell attachment to fibronectin in the medulla. In the small intestine, CCL25 is expressed by intestinal epithelium and controls segmental specialization of the intestinal immune system by recruiting gut-specific memory/effector T cells. CCL25 also promotes melanoma, ovarian cancer, breast cancer, leukemia, and prostatic carcinoma cell migration. A recent report shows that multiple myeloma cells can produce CCL25 and induce mesenchymal stromal cell migration. Bone marrow pre-pro-B cells also migrate in response to CCL25. CCL25 expression can be induced in the liver of patients with primary sclerosing cholangitis. Intestinal epithelial cell expression of CCL25 is also reduced in HIV-positive individuals.

Unopened vial can be stored at 4C for three months, at -20C for six months, or at -70C for one year. For maximum results, quick spin vial prior to opening. Stock solutions should be prepared at no less than 10 microg/mL in sterile buffer (PBS, HPBS, DPBS, and EBSS) containing carrier protein such as 1% BSA or HSA. After dilution, the cytokine can be stored at 4C for one month or from -20C to -70C for up to 3 months. Avoid repeated freeze/thaw cycles.
