- Western blot analysis of GRB2 using 30 µg of Raji lysate. Samples were loaded onto a 12% SDS-PAGE gel and probed with a GRB2 polyclonal antibody (Product # PA5-27151) at a dilution of 1:1000.

- Knockdown of GRB2 was achieved by transfecting MCF7 cells with GRB2 specific siRNAs (Silencer® select Cat # S6120 and s226232). Western blot analysis (Fig a) was performed using membrane extracts from the GRB2 knock down cells (Lane 3), non-specific scrambled siRNA transfected cells (Lane 2) and untransfected cells (Lane 1). The blots were probed with Anti-GRB2 Rabbit Polyclonal Antibody (Product # PA5-27151, 1 µg/mL) and Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). Densitometric analysis of this western blot is shown in histogram (Fig b). Loss of signal upon siRNA mediated knock down confirms that antibody is specific to GRB2.

- Western blot analysis was performed on membrane enriched extracts (30 µg lysate) of MCF7 (1), A-431 (2), H1975 (3), PC-3 (4), DU-145 (5), MDA-MB-231 (6), Ramos (7), HEK-293 (8), 3T3-L1 (9), Jurkat (10) and A549 (11). The blots were probed with Goat Anti-GRB2 Polyclonal Antibody (Product # PA5-27151, 1:2000 dilution) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25 µg/mL, 1:4000 dilution). A 25 kDa band corresponding to GRB2 was observed across the cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 12 % Bis-Tris gel (Product # NP0342BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane using iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary antibody following blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

- CRISPR-Cas9 mediated genome editing ofGRB2 (as confirmed by next generation sequencing) was achieved by using LentiArray™ Lentiviral sgRNA (Product # A32042, AssayIDCRISPR1049656_LV) and LentiArray Cas9 Lentivirus (Product # A32064). Fig (a) Western blot analysis of GRB2 was performed by loading 30 µg of HeLa Cas9 (Lane 1) and HeLa Cas9 cells transduced with GRB2 Lentiviral sgRNA (Lane 2) whole cell 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-GRB2 Polyclonal Antibody (Product # PA5-27151, 1:2000 dilution) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27037, 1:5000 dilution).Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005). A loss of signal in sgRNA transduced cells using the LentiArray™ CRISPR product line confirms that antibody is specific toGRB2 (Fig (b)).
