Application Details

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Comment:

Sequence similarities: Contains 1 galectin domain.

Plate: Pre-coated

Protocol: human Galectin-2 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for Galectin-2 has been precoated onto 96-well plates. Standards(E.coli, M1-E132) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Galectin-2 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human Galectin-2 amount of sample captured in plate.

Assay Procedure:

Aliquot 0.1 mL per well of the 10,000pg/mL, 5000pg/mL, 2500pg/mL, 1250pg/mL, 625pg/mL, 312pg/mL, 156pg/mL human Galectin-2 standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of human cell culture supernates, serum or plasma(heparin, EDTA) to each empty well. See "Sample Dilution Guideline" above for details. It is recommended that each human Galectin-2 standard solution and each sample be measured in duplicate.

Background:

Protein Function: This protein binds beta-galactoside. Its physiological function is not yet known.

Background: Galectin-2 is a protein that in humans is encoded by the LGALS2 gene. It is mapped to 22q13.1. The protein encoded by this gene is a soluble beta-galactoside binding lectin. The encoded protein is found as a homodimer and can bind to lymphotoxin-alpha. It has been found that a single-nucleotide polymorphism in Galectin-2 is significantly associated with susceptibility to myocardial infarction. This genetic substitution affects the transcriptional level of Galectin-2 in vitro, potentially leading to altered secretion of LTA, to which Galectin-2 binds, which would then affect the degree of inflammation.
