Product overview
Human ALT ELISA Kit (ab234578) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of ALT protein in cit plasma, edta plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human ALT with 47.34 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 stripsA 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
ASSAY SPECIFICITY
This kit recognizes both native and recombinant human ALT protein in serum, plasma, and cell culture supernatant samples only.
Tissue extract samples have not been tested with this kit.
This kit is incompatible with plasma- heparin and cell extract samples.
SPECIES REACTIVITY This kit recognizes human ALT protein. Other species reactivity not determined. Please contact our Technical Support team for more information. -
Notes
ALT (Alanine aminotransferase 1, ALT1) is an aminotransferase that plays a key role in metabolism. It forms pyruvate through the reversible transamination of alanine and 2-oxoglutarate; this reaction is pivotal for gluconeogenesis and amino acid degradation. It is part of a key blood panel diagnostic that is indicative of liver health.

Research areas
-
Function
Catalyzes the reversible transamination between alanine and 2-oxoglutarate to form pyruvate and glutamate. Participates in cellular nitrogen metabolism and also in liver gluconeogenesis starting with precursors transported from skeletal muscles. -
Tissue specificity
Liver, kidney, heart, and skeletal muscles. Expressed at moderate levels in the adipose tissue. -
Pathway
Amino-acid degradation; L-alanine degradation via transaminase pathway; pyruvate from L-alanine: step 1/1. -
Sequence similarities
Belongs to the class-I pyridoxal-phosphate-dependent aminotransferase family. Alanine aminotransferase subfamily. -

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.

The ALT standard curve was prepared as described in Section 10. Raw data values are shown in the table. Background-subtracted data values (mean +/- SD) are graphed.

Example of human ALT standard curve in Sample Diluent NS + 1X Enhancer. The ALT standard curve was prepared as described. Raw data values are shown in the table. Background-subtracted data values (mean +/- SD) are graphed.
-
The concentrations of ALT were measured in duplicates, interpolated from the ALT standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 25%, plasma (citrate) 25%, and plasma (EDTA) 25%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean ALT concentration was determined to be 4,002.9 pg/mL in serum, 2,685.5 pg/mL in plasma (EDTA) and 1,886.6 pg/mL in plasma (citrate).
-
Linearity of dilution is determined based on interpolated values from the standard curve. Linearity of dilution defines a sample concentration interval in which interpolated target concentrations are directly proportional to sample dilution.
Native ALT was measured in the following biological samples in a 2-fold dilution series. Sample dilutions are made in Sample Diluent NS + 1X Enhancer.
-
Recombinant ALT was spiked into the following biological samples and diluted in a 2-fold dilution series in Sample Diluent NS + 1X Enhancer.
