• Product name
    Anti-hCG beta antibody [5H4-E2]
    See all hCG beta primary antibodies
  • Description
    Mouse monoclonal [5H4-E2] to hCG beta
  • Host species
  • Specificity
    The antibody recognizes the whole hCG beta and the C-terminal end part of hCG beta, as well as the hCG dimer molecule. It does not react with hCG alpha, FSH, LH, TSH and albumins (evaluated by simple-binding ELISA using 1.00 µg/well purified antigens (WHO standards) and 1.00 µg/ml primary antibody concentrations). This antibody labels the cytoplasm of hCG beta producing (trophoblastic) cells in placenta, mola hydatidosa, choriocarcinoma, embryonal carcinoma and some undifferenciated lung cancers, as well as, the JAR choriocarcinoma cell line. It does not react with cells of normal endometrial, testicular tissues and lung (tested by immunohistochemistry on formalin-fixed, paraffin-embedded tissue sections using the Streptavidin-biotinylated peroxidase method).

Our Abpromise guarantee covers the use of ab9582 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use at an assay dependent concentration.
ELISA Use at an assay dependent concentration.
IHC-P Use at an assay dependent concentration. It gives optimal immunostaining with the majority of well-known detection systems (e.g. LSAB, ABC/SABC, PAP, APAAP, double staining, etc.). Antigen retrieval, such as heating of slides in 10 mM citrate buffer, pH 6.00 or proteolytic pre-treatment of tissues may increase the staining intensity. The recommended time of incubation is 60 minutes at room temperature.
IHC-Fr Use at an assay dependent concentration.
ICC Use at an assay dependent concentration.
ICC/IF Use at an assay dependent concentration.



  • Formalin-fixed, paraffin-embedded human seminoma tissue stained for hCG beta with ab9582 at a 1/50 dilution in immunohistochemical analysis.

  • ab9582 at 1/100 dilution staining hCG beta in human chorionic villus cells by Immunocytochemistry/ Immunofluorescence. Cells were fixed in paraformaldehyde, without permeabilization and blocked in 3% BSA for 1 hour at 25°C. The primary antibody was diluted in PBS (3% BSA) and incubated with sample at 4°C for 12 hours. An Alexa Fluor® 568 conjugated Goat polyclonal to mouse IgG was used at 1/500 dilution as secondary. Image A show DAPI staining, B show staining with ab9582 and C is the merged image which show staining with DAPI and ab9582 together.

  • ab9582 staining hCG beta in human fetal chorionic villus by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Samples were fixed in 4% paraformaldehyde and then incubated with ab9582 in PBT [3% bovine serum albumin (BSA) and 0.5% Triton X-100 in phosphate-buffered saline (PBS)] overnight at 4°C. After extensive washing with PBT, samples were incubated with a secondary antibody conjugated to Alexa-Fluor® 488 for 1 hour at room temperature in the dark. After nuclear staining with Hoechst slides were mounted with PBS/ glycerol.

Thank you for your enquiry and your interest in our products.

I can confirm that ab9582 (Anti-hCG beta antibody [5H4-E2]), has not been tested for IP yet, though the isotype has been determined (IgG1).

Normally, we would suggest usi...

Thank you for your enquiries.

I can confirm that ab9582hCG beta antibody was raised against the beta subunit ofhCG only, and its reactivity was blocked by betasubunit of hCG, notthe alpha subunit. Therefore, we would not expect it to detect ...

Thank you for your feedback regarding ab9582. You mention a band at a molecular weight similar to that of albumin, is this around 60-70KDa? I think the MW for albumin is about 66KDa. Could this band be explained by the fact the antibody recognizes th...
