Hsp73 is a normal cell constituent which is synthesized in increased abundance under adverse environmental circumstances, such as non-physiological temperatures or treatment with amino acid analogues (1). Data has shown a molecular mechanism for cytokine-mediated posttranscriptional regulation of Bim mRNA by Hsc70, which binds to AU-rich elements (AREs) in the 3'-untranslated region of specific mRNAs and enhances their stability. The RNA binding potential of Hsc70 is regulated by cochaperones including Bag-4 (also SODD), CHIP, Hip, and Hsp40 (2). Hsp73 protein expression was detected in the cytoplasm of melanoma cells in primary tumors and metastases. In primary melanomas, the proportion of Hsp73 protein expressing cells correlated with tumor thickness which was found to be statistically significant.
Suitable for use in Flow Cytometry, ELISA, Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested.
Flow Cytometry: 1:30
Western Blot: 1:500
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
