SKU:: 172108-AF
Reinheit:: Purified by Protein A/G affinity chromatography.
Lagerbedingungen:: -20°C
Hersteller:: 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
Klon:: SPM252
Format:: Supplied as a liquid in PBS. Also available with BSA and azide, see 172108.
Weitere Details:: It recognizes a 24-27kD 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: 0.25-0.5ug/ml Immunoprecipitation: 0.5-1µg/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 dilution for a specific application should be determined. 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: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
