Western Blot

0.25 - 1 ug/ml
Application Notes
GAPDH is a widely used loading control for quantitative Western blotting. In IHC-P, the staining of formalin-fixed tissues is enhanced by boiling tissue sections in 10 mM sodium citrate buffer, pH 6.0 for 10-20 min followed by cooling at RT for 20 min.

In Simple Western only 10 - 15 uL of the recommended dilution is used per data point. Separated by Size-Wes, Sally Sue/Peggy Sue. WB reported in a verified customer review.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: GAPDH

Glyceraldehyde 3-Phosphate Dehydrogenase (GAPDH) is a ubiquitous enzyme involved in glycolysis, converting glyceraldehyde-3-phosphate into 1,3 diphosphoglycerate. This constitutively expressed, homotetramer protein can be found in the nucleus and cytoplasm, and the monomer has a theoretical molecular weight of 36 kDa. Known as a housekeeping gene, GAPDH routinely serves as a control for real-time PCR (RT-PCR) and as a loading control for Western Blots (1-3). In addition to its role in glycolysis, GAPDH has multiple cellular functions including membrane trafficking, transcription activation, apoptosis, DNA repair, and has been implicated in various pathologies such as cancer and neurodegenerative diseases including Alzheimer's and Huntington's (4,5).

FAQs for GAPDH Antibody (13H12) - BSA Free

Showing  1 - 2 of 2 FAQs Showing All
  • Q: I have GAPDH Antibody (NBP2-27103). According to the datasheet it is monoclonal. I want to do IF staining. Can it be stained with goat anti-rabbit IgG-FITC.

    A: Our GAPDH antibody with catalogue number NBP2-27103 has been validated for immunofluorescence. Our own immunofluorescence testing data was generated in HeLa cells; detection was with a Dylight 488-conjugated anti-mouse secondary antibody. Since NBP2-27103 is a mouse antibody you will need to use an anti-mouse secondary antibody for detection; a goat anti-rabbit antibody will not be suitable. NBP2-27103 is of the isotype IgG1 kappa, and you can see our anti-mouse IgG1 secondary antibodies at the following link: anti-mouse IgG1 secondary antibodies You can use the search filters at the left hand side of our webpage to select your conjugate of choice.

  • Q: I have a question about NBP2-27103 GAPDH ab for Simple Western Wes system. In the application note "In Simple Western only 10 - 15 uL of the recommended dilution is used per data point." What do you mean 10-15 micro L of dilution?

    A: It means to use only 10-15 ul of the diluted stock. Dilute from 0.25- 1 ug/ml then use 10- 15 ul on the column.
