SKU:: 168677-AF-HRP
Reinheit:: Purified by Protein A/G affinity chromatography.
Lagerbedingungen:: -20°C
Hersteller:: United States Biological
Host:: Mouse
Immunogen:: Lymphoblastoid cell line Daudi. Cellular Localization: Predominantly cell surface with some cytoplasmic
Klon:: B9E9
Format:: Supplied as a liquid in 10mM PBS. No preservative added. BSA-Free. Labeled with horseradish peroxidase (HRP).
Weitere Details:: Recognizes a protein of 33-37kDa, identified as CD20 (Workshop V; Code CD20.12). B9E9 recognizes extracellular domain of CD20. The epitope is similar to or identical to that recognized by other CD20 antibodies including Leu-16 and B1. This MAb can be used for immunophenotyping of leukemia and malignant cells, B lymphocyte detection in peripheral blood, B cell localization in tissues and B lymphocyte purification by immunosorbent methods. CD20 is a non-Ig differentiation antigen of B-cells and its expression is restricted to normal and neoplastic B-cells, being absent from all other leukocytes and tissues. CD20 is expressed by pre B-cells and persists during all stages of B-cell maturation but is lost upon terminal differentiation into plasma cells. Protein passes through the membrane 4 times with both ends in cytoplasm and exposes one short and one longer loop to the external environment. CD20 is not glycosylated in resting B cells and its cytoplasmic domains are differentially phosphorylated upon activation. It acts as a calcium channel involved in B-cell activation and cell cycle progression. Applications: Suitable for use in ELISA, Immunoprecipitation, Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunoprecipitation: 0.5-1ug/500ug protein lysate Immunohistochemistry: Frozen: 0.5-1.0ug/ml for 30 minutes at RT Optimal dilutions to be determined by the researcher. Positive Control: Daudi, Raji, and U266, and human lymphocytes. In normal lymph nodes and tonsils, CD20 is predominantly detected on B cells in germinal centers. Storage and Stability: Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Note: Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
