Components:

45x Ab-conjugated beads (S5P11 - mouse SCF/MGF/KITLG ab-bead). PN: B211267A. One vial containing 100 µL of anti-mouse SCF/MGF/KITLG conjugated to AimPlex Bead S5P11.

25x Biotin-detection Ab (Mouse SCF/MGF/KITLG Biotin-dAb). PN: B211267B. One vial containing 100 µL of biotinylated anti-mouse SCF/MGF/KITLG.

Lyophilized Standard - Mouse SCF/MGF/KITLG. PN: B211267S. One vial containing lyophilized recombinant mouse SCF/MGF/KITLG.  

Application: Optimal antibody pair and antigen standard for assaying mouse SCF/MGF/KITLG. To be used in conjunction with the AimPlex Mouse/Rat Basic Kit (PN: P200201) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

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.

Description:

Stem cell factor (SCF)/mast cell growth factor (MGF) or kit ligand (Accession P21583), like CX3CL1 can exist as both a transmembrane and soluble protein. SCF is vital to hematopoiesis (especially during embryonic development), spermatogenesis, and melanogenesis. For normal hematopoiesis, both transmembrane and soluble forms must be present. SCF is expressed by stromal cells and fibroblasts. It promotes chemotaxis, mast cell secretory function, and can aide mediators in responses to IgE-dependent activation. Diseases associated with this include hyperpigmentation and testicular non-seminomatous germ cell tumor.
