HSP27 (Heat Shock Protein 27, Heat shock 27kD Protein, Estrogen-regulated 24kD Protein, Heat shock 25kD Protein 1, Heat shock 28kD Protein 1, Heat shock Protein beta-1, HMN2B, Hsp25, Hsp28, HspB1, Stress-responsive Protein 27, SRP27) (APC)

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 (Not Tested), FLISA, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested.||Recommended Dilution:|Flow Cytometry (Not Tested): 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 before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only prior to immediate use. Stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer. APC is light sensitive.||Note: Applications are based on unconjugated antibody.
