CD117/c-kit Antibody (KIT/982)

Western Blot: CD117/c-kit Antibody (KIT/982) [NBP2-44761] - Recombinant fragment of CD117 with CD117 Monoclonal Antibody (KIT/982).

Protein Array: CD117/c-kit Antibody (KIT/982) [NBP2-44761] - Analysis of Protein Array containing more than 19,000 full-length human proteins using CD117/c-kit Antibody (KIT/982). Z- and S- Score: The Z-score represents the strength of a signal that a monoclonal antibody (Monoclonal Antibody) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProt(TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProt(TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a Monoclonal Antibody to its intended target. A Monoclonal Antibody is considered to specific to its intended target, if the Monoclonal Antibody has an S-score of at least 2.5.

CD117/c-kit Antibody (KIT/982) Summary

• Immunogen: Recombinant fragment (around aa100-300) of human CD117/c-kit protein (exact sequence is proprietary) (Uniprot: P10721)
• Localization: Cell surface and cytoplasmic
• Marker: Marker for Gastrointestinal Stromal Tumors
• Specificity: This monoclonal antibody recognizes a protein of 145kDa, identified as CD117/p145kit. It is found on a wide variety of tumor cells including follicular and papillary carcinoma of thyroid, adenocarcinomas from endometrium, lung, ovary, pancreas, and breast as well as malignant melanoma, endodermal sinus tumor, and small cell carcinoma. However, anti-CD117 has been particularly useful in differentiating gastrointestinal stromal tumors from Kaposis sarcoma, tumors of smooth muscle origin, fibromatosis, and neural tumors of the GI tract. Anti-CD117 is also useful in recognizing myeloblasts in bone marrow biopsy and clot section.

Background

CD117 is a 145 kD immunoglobulin superfamily member, also known as c-Kit and stem cell factor receptor (SCFR). It is a transmembrane tyrosine-kinase receptor that binds the c-Kit ligand (also known as steel factor, stem cell factor, and mast cell growth factor). CD117 is expressed on hematopoietic stem cells (including multipotent hematopoietic stem cells, progenitors committed to myeloid and/or erythroid lineages, and T and B cell precursors), mast cells, and acute myeloid leukemia (AML) cells. CD117 interaction with it's ligand is critical for the development of hematopoietic stem cells. The 2B8 antibody does not block c-Kit activity.
