G3BP1 Antibody in Immunocytochemistry (ICC/IF) — Immunofluorescence analysis of G3BP1 was performed using 70% confluent log phase U-2 OS treated with Heat Shock (45 degree celsius, 45 minutes). The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 2% BSA for 45 minutes at room temperature. The cells were labeled with G3BP1 Polyclonal Antibody (Product # PA5-29455) at 1:200 dilution in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Donkey anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32790), (1:2000 dilution), for 45 minutes at room temperature (Panel a: Green). Nuclei (Panel b:Blue) were stained with ProLong™ Diamond Antifade Mountant with DAPI (Product # P36962). F-actin (Panel c: Red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing localization of G3BP1 to stress granules. Panel e represents untreated cells exhibiting cytoplasmic localization. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60x magnification.

G3BP1 Antibody in Immunohistochemistry (Paraffin) (IHC (P)) — Immunohistochemical analysis of G3BP1 in paraffin-embedded HeLa xenograft using a G3BP1 polyclonal antibody (Product # PA5-29455) at a dilution of 1:500.

G3BP1 Antibody in Western Blot (WB) — Western blot was performed using Anti-G3BP1 Polyclonal Antibody (Product # PA5-29455) and a 70kDa band corresponding to G3BP1 was observed across all cell lines tested. Whole cell extracts (30 µg lysate) of HEK-293 (Lane 1), HeLa (Lane 2), Hep G2 (Lane 3), MCF7 (Lane 4), A-431 (Lane 5) and U-2 OS (Lane 6) 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 (1:10,000 dilution) 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).

G3BP1 Antibody — Antibody specificity was demonstrated by siRNA mediated knockdown of the target protein. HeLa cells were transfected with G3BP1 specific siRNA and decrease in signal intensity was observed in Western Blot application using Anti-G3BP1 Polyclonal Antibody (Product # PA5-29455). {KD}

Target Information

This gene encodes one of the DNA-unwinding enzymes which prefers partially unwound 3'-tailed substrates and can also unwind partial RNA/DNA and RNA/RNA duplexes in an ATP-dependent fashion. This enzyme is a member of the heterogeneous nuclear RNA-binding proteins and is also an element of the Ras signal transduction pathway. It binds specifically to the Ras-GTPase-activating protein by associating with its SH3 domain. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.

Molecular and cellular biology

Yang M,Gallo-Ebert C,Hayward M,Liu W,McDonough V,Nickels JT

PA5-29455 was used in Western Blotting to support the hypothesis that IGF2BP2 has an important role in maintaining lipid homeostasis through its modulation of ABCA1 expression, as its overexpression or loss leads to dyslipidemia.
