How the assay works
Human Lactate Dehydrogenase B / LDH-B SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

Functional lactate dehydrogenase are homo or hetero tetramers composed of M and H protein subunits encoded by the LDH-A and LDH-B genes, respectively. The major isozymes of skeletal muscle and liver has four muscle (M) subunits; while the main isozymes for heart muscle contains four (H) subunits. The other variants contain both types of subunits. LDHB converts pyruvate to lactate under low oxygen conditions, while in the LDH-A converts lactate into pyruvate. Elevated levels of LDH indicate tissue breakdown in hemolysis. LDH can be used as a marker of myocardial infarction, peaking at days 3 and lasting through day 10. Other disorders indicated by elevated LDH include cancer, meningitis, encephalitis, acute pancreatitis, and HIV. Defects in LDHB are a cause of hereditary LDH-B deficiency; however LDH-B deficiency is usually asymptomatic.

Lactate Dehydrogenase B (LDH-B) also known as LDH is an enzyme that plays an important role in the interconversion of lactate to pyruvate. It belongs to the lactate dehydrogenase family which includes multiple isoenzymes. LDH-B has a molecular weight of approximately 36 kDa and commonly forms a tetramer with three other similar subunits. It is mainly expressed in heart and muscle tissues among others where it functions effectively.
Biological function summary
LDH-B is essential for cellular energy production processes. It catalyzes the conversion of pyruvate a byproduct of glycolysis into lactate while simultaneously converting NADH to NAD+. This reaction is significant under anaerobic conditions where mitochondria-based ATP production is limited. LDH-B does not function alone and can operate as part of the lactate dehydrogenase complex containing different subunit combinations.
Pathways
Lactate and pyruvate metabolism engage LDH-B facilitating the Cori cycle and the lactate shuttle. These pathways enable lactate transport between tissues such as muscle and liver and they are important in maintaining blood glucose levels and energy balance. LDH-B operates alongside its related isoenzymes such as LDH-A which predominantly act in specific tissues and conditions to optimize energy utilization.
Anomalous LDH-B activity associates with conditions like myocardial infarction and some cancer types. Enhanced expression or activity of LDH-B can indicate altered metabolic states in tumors connecting it as a potential marker for certain cancerous conditions. The relationship with other proteins such as the hypoxia-inducible factor (HIF) is notable especially in cancer where HIF can regulate LDH-B expression under low oxygen environments.
