45x Ab-conjugated beads (S4P5 - NHP SDF-1 Ab-bead). PN: B412245A. One vial containing 100 µL of anti-NHP SDF-1 conjugated to AimPlex Bead S4P5.
25x Biotin-detection Ab (NHP SDF-1 Biotin-dAb). PN: B412245B. One vial containing 100 µL of biotinylated anti-NHP SDF-1.
Lyophilized Standard - NHP SDF-1. PN: B412245S. One vial containing lyophilized recombinant SDF-1.
Application: Optimal antibody pair and antigen standard for assaying NHP CXCL12/SDF-1. To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure. Note: SDF-1 binds to CXCR4 with high affinity. CXCR4 is expressed on platelets. Sample types containing low levels of platelets such as platelet-poor plasma are recommended.
Storage: 2-8 C in the dark.
Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Stromal cell-derived factor 1 (SDF-1) also known as C-X-C motif chemokine 12 (CXCL12 is a small cytokine that belongs to the chemokine family, members of which activate leukocytes and are often induced by pro-inflammatory stimuli such as lipopolysaccharide, TNF, or IL1. CXCL12 is strongly chemotactic for lymphocytes. During embryogenesis it directs the migration of hematopoietic cells from fetal liver to bone marrow and the formation of large blood vessels. In adulthood, CXCL12 plays an important role in angiogenesis by recruiting endothelial progenitor cells (EPCs) from the bone marrow through a CXCR4 dependent mechanism. It is this function of CXCL12 that makes it a very important factor in carcinogenesis and the neovascularisation linked to tumor progression. CXCL12 also has a role in tumor metastasis where cancer cells that express the receptor CXCR4 are attracted to metastasis target tissues that release the ligand, CXCL12. In breast cancer, however, increased expression of CXCL12 determines a reduced risk of distant metastasis. CXCL12 is shown to be responsible for recruiting macrophages to breast tumors in mice in response to the experimental anti-cancer drug combretastatin A-4 phosphate, which damages tumor blood vessels. Diseases associated with CXCL12 include Retinal Hemangioblastoma and Whim Syndrome.
