The isozyme of lactate dehydrogenase (LDH) that is specific to testes, designated LDH-C4, is the predominant LDH isozyme in mammalian spermatozoa. Four high-affinity monoclonal antibodies have been developed to murine LDH-C4. These antibodies were tested for crossreactivity with LDH-C4 from rat, hamster, rabbit, and human by competitive binding radioimmunoassays. Monoclonal antibodies RG-1 and ...

Layered double hydroxide (LDH)@SiO2 nanoparticles were developed as a delivery carrier for the plasmid DNA expressing the Newcastle disease virus F gene. The LDH was hydrotalcite-like materials. The plasmid DNA encapsulated in the LDH@SiO2 nanoparticles (pFDNA-LDH@SiO2-NPs) was prepared by the coprecipitation method, and the properties of pFDNA-LDH@SiO2-NPs were characterized by transmission el...

Lactate dehydrogenase (LDH: 3.1.1.27) is a tetrameric enzyme participates in carbohydrate metabolism by catalyzing the oxidation of lactate and reduction of pyruvate. The random tetramerization of LDH-A and -B subunits leads to the formation of five tetramers: LDHB4, LDH-A1B3, LDH-A2B2, LDH-A3B1 and LDH-A4. Due to the biochemical and evolutionary significance of LDH isoenzyme characters or LDH ...

Lactate dehydrogenase (LDH; E.C. 1.1.1.27) is a crucial enzyme involved in energy metabolism in muscle, facilitating the production of ATP via glycolysis during oxygen deprivation by recycling NAD(+). The present study investigated purified LDH from the muscle of 20 h anoxic and normoxic T. s. elegans, and LDH from anoxic muscle showed a significantly lower (47%) K m for L-lactate and a higher ...

This note compares the substrate specificity of D-lactate dehydrogenase (D-LDH, EC 1.1.1.28) to that of L-lactate dehydrogenase (L-LDH, EC 1.1.1.27), illustrates three procedures that use D-LDH in synthesis and two methods for recycling NADH, and provides experimental details illustrating the use of D-LDH in organic synthesis.

The data described are related to the article entitled "Sequence Analysis of Meq oncogene among Indian isolates of Marek׳s Disease Herpesvirus" M. Gupta, D. Deka, Ramneek, 2016. Seven meq genes of Ludhiana Marek׳s disease virus (MDV) field isolates were PCR amplified by using proof reading Platinum Pfx DNA polymerase enzyme, sequenced and then analyzed for the distinct polymorphisms and point m...

PURPOSE To investigate the relationship between lactate dehydrogenase A (LDH-A) expression, lactate concentration, cell metabolism, and metastases in murine 4T1 breast tumors. EXPERIMENTAL DESIGN Inhibition of LDH-A expression and protein levels were achieved in a metastatic breast cancer cell line (4T1) using short hairpin RNA (shRNA) technology. The relationship between tumor LDH-A protein ...

Preparations of pooled Friend virus used in this laboratory were found to contain lactate dehydrogenase (LDH) virus. Interrelationships between these viruses and the effects of drug treatment i~ vivo and virus neutralization in vitro were studied. Both 6-mercaptopurine and streptonigrin administered to Friend virus-infected mice delayed the onset of the 10to 100-fold normal elev,%tion of plasma...

The procedure used to determine the infective titer of the LDH agent, the reproducibility of this assay, and the relationship between virus dose and plasma enzyme activity were described. Multiplication of the LDH agent began within 6 hours after infection and reached 10(10.8) ID(50)/ml of plasma within 24 hours. The titer rapidly decreased over the next 72 hours but viremia persisted for at le...

Induction of lactic dehydrogenase (LDH) antibody with porcine LDH in L1210 leukemia-bearing DBA/2 mice can induce remissions of the disease. The concurrent, limited use of a cytotoxic agent (azathioprine) in combination with LDH has been investigated and found to be advantageous in terms of obtaining a greater number of prolonged remis sions (over 150 days) than does the use of LDH alone. The p...
