Absorbance (491nm); Emission (515nm); Extinction Coefficient 73,000. S100 belongs to the family of calcium binding proteins. S100A and S100B proteins are two members of the S100 family. S100A is composed of an alpha and beta chain whereas S100B is composed of two beta chains. S-100 protein has been found in normal melanocytes, Langerhans cells, histiocytes, chondrocytes, lipocytes, skeletal and cardiac muscle, Schwann cells, epithelial and myoepithelial cells of the breast, salivary and sweat glands, as well as in glial cells. Neoplasms derived from these cells also express S-100 protein, albeit non-uniformly. A large number of well-differentiated tumors of the salivary gland, adipose and cartilaginous tissue, and Schwann cell-derived tumors express S-100 protein. Almost all malignant melanomas and cases of histiocytosis X are positive for S-100 protein. Despite the fact that S-100 protein is an ubiquitous substance, its demonstration is of great value in the identification of several neoplasms, particularly melanomas and their metastases. Applications: Suitable for use in Immunofluorescence, Flow Cytometry, FLISA, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested. Recommended Dilution: Flow Cytometry: 0.5-1ug/million cells Immunofluorescence: 1-2ug/ml Western Blot: 0.5-1ug/ml Immunoprecipitation: 1-2ug/500ug protein lysate Immunohistochemistry (Frozen & Formalin-fixed): 0.5-1ug/ml for 30 minutes at RT (No special pretreatment is required for IHC staining of formalin-paraffin tissues) Optimal dilution for a specific application should be determined. Positive Control: Brain, Melanoma Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™490 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
