Human Hsp27, mouse Hsp25 and αβ-crystallin are part of a diverse family of small heat shock proteins which are produced in all organisms. They function as chaperone-like proteins by binding unfolded polypeptides and preventing uncontrolled protein aggregation. Hsp27 is believed to exist mainly as oligomers of as many as 8-40 Hsp27 protein monomers in cells and data sμggests that the large oligomers of Hsp27 have a chaperone-like activity by serving as a site where unfolding proteins may bind until ATP and Hsp70-dependent refolding can occur. Hsp27 is believed to protect cells by enhancing cellular glutathione levels and elevated glutathione levels have been measured in cells overexpressing Hsp27. Data from studies using wild-type Hsp27 and mutant forms in which the serine phosphorylation sites were mutated to alanines, glycines or aspartates, have shown that cellular glutathione levels depend on the oligomerization of Hsp27. Recent findings indicate that Hsp27 is also a negative regulator of cytochrome c-dependent activation of procaspase-3.

Rabbit

Polyclonal

Rabbit IgG

Human, monkey

Recombinant human Hsp27

0.2 mg/ml

Liquid

100 µg (200 µg/ml) in phosphate buffered saline (PBS), pH 7.2, containing 50% glycerol, 1% BSA, 0.02% thimerosal.

Affinity purified

Western blot, Immunoprecipitation, Immunofluorescence

Western blotting (1-2 µg/ml), immunoprecipitation (5-10 µg/ml), immunocytochemistry (10-15 µg/ml), and ELISA (1 µg/ml). However, the optimal conditions should be determined individually. The antibody detects a 27 kDa protein, corresponding to the apparent molecular mass of Hsp27 on SDS-PAGE immunoblots, in samples from human, monkey, dog (weakly) and pig (weakly) origins.

Shelf time: 12 months in temp.: -20 deg.C

gel pack

The antibody solution should be gently mixed before use.

This antibody needs to be stored at + 4°C in a fridge short term in a concentrated dilution. Freeze thaw will destroy a percentage in every cycle and should be avoided.

If you buy Antibodies supplied by Biovision they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
