Anti-Mouse c-Kit/CD117 (ACK2) ColorWheel^® Dye-Ready mAb

ColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^® antibody with any ColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^® antibody and dye is lyophilized for long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^® technology requires both ColorWheel^® antibody and ColorWheel^® dye for Flow Cytometry application.

Mast/stem cell growth factor receptor Kit (UniProt: P05532; also known as EC:2.7.10.1, SCFR, Proto-oncogene c-Kit, Tyrosine-protein kinase Kit, CD117) is encoded by the Kit (also known as SI) gene (Gene ID: 16590) in murine species. c-Kit is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-24), which is subsequently cleaved off to generate the mature form that contains an extracellular domain (aa 25-527), a transmembrane domain (aa 528-548), and a cytoplasmic domain (aa 549-979). c-Kit has tyrosine protein kinase activity and serves as a cell-surface receptor for the stem cell factor (SCF)/KITLG. It plays a significant role in the regulation of cell survival, cell proliferation, stem cell maintenance, gametogenesis and other functions. In response to SCF binding, c-Kit can activate several signaling pathways. In the absence of bound SCF, it exists as a monomer, however, it homodimerizes in the presence of bound SCF and forms a heterotetramer with two SCF molecules. c-Kit can be autophosphorylated on tyrosine residues and SCF binding enhances its autophosphorylation. Its kinase activity is reported to be down-regulated by phosphorylation on serine residues by protein kinase C family members. Phosphorylation at Tyr 571 is shown to be essential for its interaction with PTPN11/SHP-2 and phosphorylation of Tyr 573 is required for interaction with PTPN6/SHP-1. c-Kit can be ubiquitinated by SOCS6 and it is rapidly ubiquitinated after autophosphorylation induced by SCF binding, leading to its internalization and degradation. Lack of c-Kit expression has been reported in multiple cancer types and c-Kit expressing cells display a regression of typical morphological features of malignancy. (Ref.: Foster, BM., et al. (2018).

Quality Control Testing

Evaluated by Flow Cytometry in Mouse Bone Marrow Cells.

Flow Cytometry Analysis: Staining of one million C57BL/6 mouse bone marrow cells was performed with APC-conjugated anti-mouse CD45R and with 5 μL of a 1:1 mixture of Cat. No. CWA-1133, Anti-Mouse c-Kit/CD117 (ACK2) ColorWheelColorWheel^® Dye-Ready mAb and Cat. No. CWDS-PE ColorWheelColorWheel^® Antibody-Ready Phycoerythrin (PE) Dye (right figure) or an equivalent amount of PE-conjugated Rat IgG2b isotype control. More CD117 expressing cells were observed in CD45R- population than in CD45R+ population.
