Experimental details: Western blot analysis of beta-2 Microglobulin was performed by separating 50 µg of mouse plasma by 15% SDS-PAGE. Proteins were transferred to a membrane and probed with a beta-2 Microglobulin Polyclonal Antibody (Product # PA5-29580) at a dilution of 1:1500. The HRP-conjugated anti-rabbit IgG antibody was used to detect the primary antibody.

Experimental details: Knockout of B2M was achieved by CRISPR-Cas9 genome editing using LentiArray™ Lentiviral sgRNA (Product # A32042, Assay ID CRISPR983707_LV) and LentiArray Cas9 Lentivirus (Product # A32064). Western blot analysis of B2M was performed by loading 30 µg of HeLa Wild Type (Lane 1), HeLa Cas9 (Lane 2) andHeLa B2M 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-beta-2 Microglobulin Polyclonal Antibody (Product # PA5-29580, 1:1,000 dilution) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4,000 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 B2M.

Experimental details: Knockdown of beta-2 Microglobulin was achieved by transfecting HeLa with beta-2 Microglobulin specific siRNAs (Silencer® select Product # s1854, s1853). Western blot analysis (Fig. a) was performed using Whole cell extracts from the beta-2 Microglobulin knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with beta-2 Microglobulin Polyclonal Antibody (Product # PA5-29580, 1:500 dilution) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000 dilution). 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 beta-2 Microglobulin.

Experimental details: Western blot was performed using Anti-beta-2 Microglobulin Polyclonal Antibody (Product # PA5-29580) and a 12 kDa band corresponding to beta-2 Microglobulin was observed across in HeLa, THP-1 and U-937 but not in SH-SY5Y or NTERA-2 cell lines which are reported to express low levels of beta-2 microglobulin. Whole cell extracts (60 µg lysate) of HeLa (Lane 1), THP-1 (Lane 2), U-937 (Lane 3), SH-SY5Y (Lane 4) and NTERA-2 cl.D1 (Lane 5) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0321BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:500) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036,1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).
