Product number: MA1-40229 - Provider product page
Provider: Invitrogen Antibodies
Product name: Galectin 3 Monoclonal Antibody (B2C10)
Antibody type: Monoclonal
Antigen: Other
Description: Description: The L243 mAb reacts with the human major histocompatibility complex (MHC) class II, HLA-DR. HLA-DR is expressed on the surface of human antigen presenting cells (APC) including B cells, monocytes, macrophages, DCs, and activated T cells. HLA-DR is a heterodimeric transmembrane protein composed of alpha and beta subunits and plays an important role in the presentation of peptides to CD4^+ T lymphocytes. The L243 antibody recognizes a different epitope than the LN3 monoclonal antibody, and these antibodies do not cross-block binding to each other's respective epitopes.
Reactivity: Human, Mouse
Host: Mouse
Isotype: IgG
Antibody clone number: B2C10
Vial size: 100 µg
Concentration: 0.1 mg/mL
Storage: 4° C

Experimental details: Knockout of Galectin3 was achieved by CRISPR-Cas9 genome editing using LentiArray™ Lentiviral sgRNA (Product # A32042, Assay ID CRISPR855199_LV and CRISPR855204_LV) and LentiArray Cas9 Lentivirus (Product # A32064). Western blot analysis of Galectin3 was performed by loading 30 µg of HeLa Wild Type (Lane 1), HeLa Cas9 (Lane 2) andHela Galectin3 KO (Lane 3) membrane enriched extracts. The samples were electrophoresed using NuPAGE™ Novex™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with Anti-Galectin 3 Monoclonal Antibody (B2C10) (Product # MA1-40229, 1:200 dilution) and Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:6,000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005). Loss of signal upon CRISPR mediated knockout (KO) using the LentiArray™ CRISPR product line confirms that antibody is specific to Galectin3.

Experimental details: Western blot was performed using Anti-Galectin 3 Monoclonal Antibody (B2C10)(Product # MA1-40229) and a ~30kDa band corresponding to Galectin 3 was observed across cell lines tested . Whole cell extracts (30 µg lysate) of HeLa (Lane 1), MDA-MB-231 (Lane 2), A549 (Lane 3), PC-3 (Lane 4), U-87 MG (Lane 5), A-431 (Lane 6) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # LC2002) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:200) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177,1:4000) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

Experimental details: Knockdown of Galectin 3 was achieved by transfecting MDA-MB-231 cells with Galectin 3 specific siRNAs (Silencer® select Product # S8149, S8148). Western blot analysis (Fig. a) was performed using Whole cell extracts from the Galectin 3 knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with Galectin 3 Monoclonal Antibody (B2C10) (Product # MA1-40229, 1:100 ) and Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:4000). Densitometric analysis of this western blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to Galectin 3.
