产品概述
Human Lactate Dehydrogenase B ELISA kit (ab183367) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of LDHB protein in human serum, plasma, cell culture supernatant, cell and tissue extracts. It uses our proprietary SimpleStep ELISA® technology. Quantitate human LDHB with 8 pg/mL sensitivity.
SimpleStep ELISA® technology 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. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpeStep ELISA® kits.
Sensitivity:
Samples diluted in Sample Diluent NS - 8 pg/mL
Samples diluted in 1X Cell Extraction Buffer PTR - 212 pg/mL -
说明
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.

Interpolated values of LDHB are plotted for the indicated cell lines based on an extract load of 20 µg/mL.
-
The concentrations of LDHB were interpolated from the LDHB standard curve and corrected for sample dilution. The mean LDHB concentration was determined to be 197 ng/mL in plasma (heparin) and 173 ng/mL in serum.
-
Serum from 10 apparently healthy male donors was measured in triplicate for LDHB. The mean LDHB concentration was determined to be 161 ng/mL with a range of 56 – 226 ng/mL.

SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.
