Rabbit Anti-HSP40 (DnaJ protein homolog 1, Heat shock 40kD protein 1)
The Hsp40 (heat shock protein with molecular size of approximately 40 kDa) is one of the mammalian homologues of bacterial DnaJ heat shock protein. Ohtsuka (1993) isolated a cDNA encoding a 40-kD heat-shock protein designated HSPF1. The deduced 340-amino acid HSPF1 protein is 34% identical to E. coli DnaJ and 34% and 36% identical to HSJ1 and HSJ2, respectively. HSPF1 gene spans over 7 kb and contains 3 exons and 2 introns. HSPF1 gene is mapped to chromosome 19p13.2.
Applications
Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested.
Recommended Dilution
Immunohistochemistry: paraffin Optimal dilutions to be determined by the researcher.
Storage and Stability
Lyophilized and reconstituted products are stable for 12 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°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.
Immunogen
A synthetic peptide corresponding to a sequence at the C-terminal of human HSP40, different from the related mouse sequence by two amino acids, and from the related rat sequence by three amino acids.
Form
Supplied as a lyophilized powder from PBS, 5% BSA, 0.05% Thimerosal, 0.05% sodium azide. Reconstitutie with 200ul sterile ddH2O.
Purity
Purified by immunoaffinity chromatography.
Specificity
Recognizes human, mouse and rat HSP40. No crossreactivity with other proteins.
