This data was developed using ab53292, the same antibody clone in a different buffer formulation.

Lanes 1 - 4 : Merged signal (red and green). Green - ab53292 observed at 37 kDa. Red - loading control, ab130007 observed at 125 kDa.

ab53292 was shown to react with Lactate Dehydrogenase in wild-type HEK-293T cells. Loss of signal was observed when knockout cell line ab255403 (knockout cell lysate ab263761) was used. Wild-type and Lactate Dehydrogenase knockout samples were subjected to SDS-PAGE. ab53292 and Anti-Vinculin antibody [VIN-54] (ab130007) were incubated overnight at 4°C at 1/5000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Lanes 1 - 3 : Merged signal (red and green). Green - ab53292 observed at 37 kDa. Red - loading control, ab130007, observed at 130 kDa.

ab53292 was shown to specifically react with Lactate Dehydrogenase B in wild-type HAP1 cells as signal was lost in LDHB (Lactate Dehydrogenase B) knockout cells. Wild-type and LDHB (Lactate Dehydrogenase B) knockout samples were subjected to SDS-PAGE. ab53292 and ab130007 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/50000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

Supplementary information

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.
