Flow cytometric analysis of HeLa cells, untreated (blue) or UV-treated (green), using Phospho-HSP27 (Ser82) (D1H2F6) XP® Rabbit mAb.

Western blot analysis of extracts from HeLa cells (lane 1) or HSP27 knock-out cells (lane 2) using HSP27 (D6W5V) Rabbit mAb #95357 (upper), and α-Actinin (D6F6) XP® Rabbit mAb #6487 (lower). The absence of signal in the HSP27 knock-out HeLa cells confirms specificity of the antibody for HSP27.

Flow cytometric analysis of HT1080 cells (blue) and HeLa cells (green) using HSP27 (D6W5V) Rabbit mAb. Anti-rabbit IgG (H+L), F(ab')2 Fragment (Alexa Fluor® 488 Conjugate) #4412 was used as a secondary antibody.

Confocal immunofluorescent analysis of C2C12 cells, untreated (left) or treated with λ phosphatase (middle), and NIH/3T3 cells (right) using Phospho-HSP27 (Ser82) (D1H2F6) XP® Rabbit mAb (green). Actin filaments were labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye). Negative staining in NIH/3T3 cells is in agreement with the observation that NIH/3T3 cells do not express HSP27 under basal conditions (5,7).

Confocal immunofluorescent analysis of HeLa (left) and HT-1080 (right) cells using HSP27 (D6W5V) Rabbit mAb (green). Actin filaments were labeled with DyLight™ 554 Phalloidin #13054 (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).

Immunohistochemical analysis of paraffin-embedded human breast carcinoma, control (left) or λ phosphatase-treated (right), using Phospho-HSP27 (Ser82) (D1H2F6) XP® Rabbit mAb.

Immunoprecipitation of HSP27 from HeLa cell extracts. Lane 1 is 10% input, lane 2 is immunoprecipitated with Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is HSP27 (D6W5V) Rabbit mAb. Western blot was performed using HSP27 (G31) Mouse mAb #2402.

Immunohistochemical analysis of paraffin-embedded mouse lung using Phospho-HSP27 (Ser82) (D1H2F6) XP® Rabbit mAb.

Western blot analysis of extracts from various cell lines using HSP27 (D6W5V) Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower).

Immunohistochemical analysis of paraffin-embedded HeLa cell pellets, control (left) or UV-treated (right), using Phospho-HSP27 (Ser82) (D1H2F6) XP® Rabbit mAb.

Immunohistochemical analysis of paraffin-embedded human lung carcinoma using Phospho-HSP27 (Ser82) (D1H2F6) XP® Rabbit mAb in the presence of control peptide (left) or antigen-specific peptide (right).

Immunohistochemical analysis of paraffin-embedded human prostate carcinoma using Phospho-HSP27 (Ser82) (D1H2F6) XP® Rabbit mAb.

Western blot analysis of extracts from HeLa or HT-29 cells, untreated (-) or treated (+) with either UV (40 mJ/cm2 with 30 min recovery) or anisomycin (25 μg/mL, 30 min), using Phospho-HSP27 (Ser82) (D1H2F6) XP® Rabbit mAb.

Background

Heat shock protein (HSP) 27 is one of the small HSPs that are constitutively expressed at different levels in various cell types and tissues. Like other small HSPs, HSP27 is regulated at both the transcriptional and posttranslational levels (1). In response to stress, the HSP27 expression increases several-fold to confer cellular resistance to the adverse environmental change. HSP27 is phosphorylated at Ser15, Ser78, and Ser82 by MAPKAPK-2 as a result of the activation of the p38 MAP kinase pathway (2,3). Phosphorylation of HSP27 causes a change in its tertiary structure, which shifts from large homotypic multimers to dimers and monomers (4). It has been shown that phosphorylation and increased concentration of HSP27 modulates actin polymerization and reorganization (5,6).
