This mAb recognizes a protein of 145 kDa, identified as CD117/p145kit/c-Kit. 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/c-Kit has been particularly useful in differentiating gastrointestinal stromal tumors from Kaposi's sarcoma, tumors of smooth muscle origin, fibromatosis, and neural tumors of the GI tract. Anti-CD117/c-Kit is also useful in recognizing myeloblasts in bone marrow biopsy and clot section.
Purification
Protein G affinity chromatography
Immunogen
A recombinant human fragment around amino acids 100-300 was used as the immunogen for the c-Kit antibody.
Optimal dilution of the c-Kit antibody should be determined by the researcher.\. Flow Cytometry: 0.5-1 μg/million cells in 0.1ml,Immunofluorescence: 0.5-1 μg/mL,Western blot (0.5-1 μg/mL for 2 hours at RT),Immunohistochemistry (Frozen only): 2-4 μg/mL for 30 min at RT
