General description

The GAPDH (glyceraldehyde-3-phosphate dehydrogenase) gene is mapped to human chromosome 12p13.3 and encodes a tetramer containing identical chains. The enzyme is commonly known as glycolytic enzyme and contains a binding site for NAD+(nicotinamide adenine diphosphate) and glyceraldehyde-3-phosphate. GAPDH contributes to 10-20% of the total cellular protein and is considered to be evolutionarily conserved.

Specificity

Anti-GAPDH recognizes human, mouse, and rat GAPDH.

Immunogen

Synthetic peptide corresponding to amino acids of mouse GAPDH, conjugated to KLH via an N-terminal cysteine residue. The corresponding sequence is identical in rat and differs by two amino acids in humans.

Application

Anti-GAPDH antibody produced in rabbit is suitable as a primary antibody for western blotting using:
  • human cancer cell extract
  • extract from muscle tissue from old mice exhibiting sarcopenia
  • trabeculae or samples of the mice heart myocardium
  • mouse embryonic fibroblasts
It is suitable for immunoprecipitation using mouse NIH3T3 cell lysates with 5-10μg, for indirect immunofluorescence using rat NRK cells at a working concentration of 5-10μg/mL. It is also suitable for western blotting at a working concentration of 0.1-0.2μg/mL using a whole extract of human HeLa cells.

Biochem/physiol Actions

The enzyme glyceraldehyde-3-phosphate dehydrogenase catalyzes the reversible oxidative phosphorylation of glyceraldehyde-phosphate in the presence of inorganic phosphate and NAD, which is a critical energy-yielding step in carbohydrate metabolism. It binds to several proteins including actin, tubulin, amyloid precursor, polyglutamine peptides, DRPLA (dentatorubral-pallidoluysian atrophy), and huntingtin. GAPDH forms a part of OCA-S, the multicomponent OCT1 (octamer-motif-binding factor) coactivator complex, which is involved in the S phase-dependent histone H2B transcription. This association is responsible for linking H2B transcriptional machinery to cell cycle regulation and to the cellular metabolic state. In response to oxidative stress, GAPDH induces apoptosis.

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month.
For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

Validation of RNAi Knockdown Using Multiple Reaction Monitoring and Protein-AQUA

The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the ability to accurately determine these protein amounts remains a challenge. Fortunately, over the past decade, the field of proteomics has witnessed significant advances in the area of mass spectrometry. These advances, both in instrumentation and methodology, are providing researchers with sensitive assays for both identification and quantification of proteins within complex samples. This discussion will highlight some of these methodologies, namely the use of Multiple Reaction Monitoring (MRM) and Protein-AQUA.

Aerobic Glycolysis and the Warburg Effect

We presents an article about the Warburg effect, and how it is the enhanced conversion of glucose to lactate observed in tumor cells, even in the presence of normal levels of oxygen. Otto Heinrich Warburg demonstrated in 1924 that cancer cells show an increased dependence on glycolysis to meet their energy needs, regardless of whether they were well-oxygenated or not.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
