Plate: Pre-coated

Protocol: mouse Galectin-1 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for Galectin-1 has been precoated onto 96-well plates. Standards(E.coli, A2-E135) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Galectin-1 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 mouse Galectin-1 amount of sample captured in plate.

Assay Procedure:

Aliquot 0.1 mL per well of the 10000pg/mL, 5000pg/mL, 2500pg/mL, 1250pg/mL, 625pg/mL, 312pg/mL, 156pg/mL mouse Galectin-1 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 mouse cell culture supernates, serum or plasma(heparin, EDTA) to each empty well. See "Sample Dilution Guideline" above for details. It is recommended that each mouse Galectin-1 standard solution and each sample be measured in duplicate.

Target Details for LGALS1/Galectin 1

Target: LGALS1/Galectin 1 (LGALS1) (Lectin, Galactoside-Binding, Soluble, 1 (LGALS1))

Alternative Name: LGALS1 (LGALS1 Products)

Background:

Protein Function: May regulate apoptosis, cell proliferation and cell differentiation. Binds beta-galactoside and a wide array of complex carbohydrates. Inhibits CD45 protein phosphatase activity. Strong inducer of T-cell apoptosis (By similarity). .

Background: Galectin-1 is a protein that in humans is encoded by the LGALS1 gene.The galectins are a family of beta-galactoside-binding proteins implicated in modulating cell-cell and cell-matrix interactions. LGALS1 may act as an autocrine negative growth factor that regulates cell proliferation.Baldini et al. stated that the mouse beta-galactoside-binding protein is an autocrine regulator of cell proliferation with a role in the maintenance of G0 and in the control of G2 traverse. They found that galectin-1 was expressed in a subset of slowly dividing subventricular zone astrocytes, which included the neural stem cells. Intraventricular infusion experiments and phenotypic analysis of knockout mice showed that galectin-1 was an endogenous factor that promoted the proliferation of neural stem cells in adult mouse brain. The standard product used in this kit is recombinant mouse GALECTIN-1, Ala2-Glu135, with the molecular mass of 15KDa.
