SKU:: 168796-AF-BIOTIN
Purity:: Purified by Protein A/G affinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Mouse
Immunogen:: Partially purified hsp27 (earlier called 24K) protein from breast cancer MCF-7 cells. Cellular Localization: Predominantly cytoplasmic with some nuclear
Clone:: G3.1
Format:: Supplied as a liquid in 10mM PBS. No preservative added. BSA-Free. Labeled with Biotin.
Extra Details:: It recognizes a 24-27kDa estrogen-regulated protein, identified as heat shock protein 27 (hsp27). Hsp27 was recently found to be identical to the estrogen-induced “p29” and “24K” protein. About 50% of breast carcinomas are positive for hsp27 especially those that are also positive for estrogen and/or progesterone receptor. HSP27 has also been implicated in drug resistance in cancer cells. Applications: Suitable for use in Immunofluorescence, Flow Cytometry, ELISA, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested. Recommended Dilution: Flow Cytometry: 0.5-1ug/million cells Immunofluorescence: 0.5-1ug/ml Western Blot: 0.5-1ug/ml Immunoprecipitation: 0.5-1ug/500ug protein lysate Immunohistochemistry: Frozen & Formalin-fixed: 0.5-1ug/ml for 30 minutes at RT (Staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10mM Citrate Buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes Optimal dilutions to be determined by the researcher. Positive Control: ~50% of Breast Carcinomas are positive for hsp27 especially those that are also positive for estrogen and/or progesterone receptor. 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. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
