GAPDH

Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is a 37KDa glycolytic enzyme constitutively and stably expressed in almost all tissues. This enzyme catalyzes the sixth step of glycolysis by converting D-glyceraldehyde 3-phosphate (G3P) into 3-phospho-D-glyceroyl phosphate. Proteins such as GAPDH involved in maintenance of basic cellular function are often referred to as housekeeping proteins. Housekeeping proteins are frequently used as loading controls for western blots and protein normalization.

Glyceraldehyde 3-phosphate dehydrogenase

The antibody recognizes native and denatured forms of GAPDH.

GA1R

IgG1

None

Purified with protein G, stored in PBS pH 7.4 and lyophilized.

If reconstituted with deionized water in 100 µl: WB 1:1000-2,000, IHC 1:500-2000. Optimal dilution has to be determined by the user.

Research Use Only

Lyophilized antibodies can be kept at 4ºC for up to 3 months and should be kept at -20ºC for long-term storage (2 years). To avoid freeze-thaw cycles, reconstituted antibodies should be aliquoted before freezing for long-term (1 year) storage (-80ºC) or kept at 4ºC for short-term usage (2 months). For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made with the assay buffer. After the maximum long-term storage period (2 years lyophilized or 1 year reconstituted) antibodies should be tested in your assay with a standard sample to verify if you have noticed any decrease in their efficacy. To limit antibody loss or degradation, BSA (final concentration 1%) and sodium azide (final concentration 0.02%) can be added to the suggested first dilution. It is important to first verify if those preservatives are compatible with your assay.
