Technical Data
DnaJ (HSP40, HDJ 2)
HDJ 2 is a novel human homolog of E. colis DNAJ protein from heat shock protein 40 family. HSP40 is involved in chaperonic protein folding. HDJ 2 is cytoplasmic and a nuclear membrane associated protein. Upon heat shock it migrates and becomes associated with the Golgi complex, nucleolus and nuclear membrane. HDJ 2 has a prenylated C-terminus and is not inducible upon heat shock.

Suitable for use in Flow Cytometry, Immunofluorescence, Immunoprecipitation, Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunoprecipitation: 2ug/mg protein lysate (native and denatured). Use Protein G.
Western Blot: 0.5-1ug/ml for 2hr at RT.
Immunohistochemistry (Formalin/paraffin): 1-2ug/ml for 30 min at RT. Staining of formalin/paraffin 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 min.
Optimal dilutions to be determined by the researcher.

Positive Control:
MAD109, Raji cells. Tonsil.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
