  • Primary antibody说明

    Heat shock proteins (HSP) are expressed in response to various biological stresses, including heat. HSP 90 is a 90 kDa protein that is induced under stress conditions, but is also one of the most abundant cellular proteins found under non-stress conditions. HSP 90 has been found to be associated with a number of other intracellular proteins, including steroid receptors, actin, tubulin, Ah receptor, and some kinases. Studies have shown that murine HSP 90 exists as two forms, HSP 84 and HSP 86, coded by related but separate genes, with 86% homologous amino acid sequences. These forms are analogous to the two forms of human HSP 90, HSP 89 beta and HSP 89 alpha. In an unstressed mouse fibroblast, the basal level of HSP 84 is found to be double that of HSP 86. However, after heat shock, HSP 86 shows a greater increase. Studies also suggest that upon cellular differentiation, the level of HSP 86, but not HSP 84, decreases. HSP 84 and HSP 86, which may be subject to estrogenic regulation, have been found as components of the non-DNA binding form of mouse glucocorticoid receptor, but dissociated from the transformed DNA-binding form.

WB
1/500 - 1/2000. Detects a band of approximately 86 kDa.
IP
Use at an assay dependent concentration.

Use at 2 μg.

Immunoprecipitation experiments with this antibody suggest that HSP90 alpha exists primarily as homodimers in HeLa cells. This antibody is capable of precipitating HSP90 alpha that is complexed with other proteins such as the aryl hydrocarbon (Ah) receptor.

    Immunocytochemistry analysis of HeLa cells labeling HSP90 alpha with ab2928 at 5ug/mL in 0.1% BSA, incubated at 4ºC overnight. Cells were 70% confluent log phase. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. Cells were then labeled with Goat anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 at 1/2000, for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI. F-actin (Panel c: Red) was stained with Rhodamine Phalloidin 1/300). Panel d represents the merged image showing cytoplasm and weak Nucleus localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

To expose target proteins, heat-induced epitope retrieval was performed using 10mM sodium citrate (pH 6.0) buffer for 20 minutes at 95ºC. Tissues were blocked in 3% BSA in PBST for 30 minutes at room temperature. Tissue sections were incubated with the primary antibody (1:100) for 1 hour. A HRP-conjugated goat anti-rabbit IgG (1:250) was used as the secondary antibody, followed by colorimetric detection using Metal Enhanced DAB Substrate Kit. Tissues were counterstained with hematoxylin and prepped for mouting. Images were taken at 40X magnification.

    Immunoprecipitation - Anti-Hsp90 alpha antibody (ab2928)

    Immunoprecipitation of HSP90 alpha was performed on HeLa (Human epithelial cell line from cervix adenocarcinoma) cells. Antigen-antibody complexes formed by incubating 500ug whole cell lysate with 2ug of ab2928 overnight on a rocking platform at 4°C. The immune complexes were captured on 50ul Protein A/G Plus Agarose, washed extensively, and eluted with buffer. Samples were then resolved on a 4-20% Tris-HCl polyacrylamide gel, transferred to a PVDF membrane and blocked with 5% BSA/TBST for at least 1 hour. The membrane was probed with ab2928 at a dilution of 1:1000 overnight rotating at 4°C. The membrane was washed in TBST, and probed with detection reagent at a dilution of 1:1000 for at least 1 hour. Chemiluminescent detection was performed.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Hsp90 alpha antibody (ab2928)

    Immunohistochemistry was performed on both normal and cancer biopsies of deparaffinized human breast carcinoma tissues. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:50 with a rabbit polyclonal antibody recognizing Heat Shock Protein 90 (86) ab2928 or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.
