SQSTM1 Antibody in Immunofluorescence (IF) — Immunofluorescent analysis of rat spleen cells using a SQSTM1 polyclonal antibody (Product # PA5-20839) at a 20 µg/mL dilution.

SQSTM1 Antibody in Immunocytochemistry (ICC) — Immunofluorescence analysis of SQSTM1 was performed using 70% confluent log phase HeLa cells. 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 SQSTM1 Polyclonal Antibody (Product # PA5-20839) at 20 µg/mL in 0.1% BSA, incubated at 4 degree celsius overnight and then labeled with Goat anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32731), (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 dilution). Panel d represents the merged image showing cytoplasmic, Endosome-like, plasma membrane and nuclear localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

SQSTM1 Antibody in Immunohistochemistry (IHC) — Immunohistochemical staining of rat spleen tissue using a SQSTM1 polyclonal antibody (Product # PA5-20839) at a 5 µg/mL dilution.

SQSTM1 Antibody in Western Blot (WB) — Western blot was performed using Anti-SQSTM1 Polyclonal Antibody (Product # PA5-20839) and a ~55 kDa band corresponding to SQSTM1 was observed across cell lines and tissue tested. Whole cell extracts (30 µg lysate) of HeLa (Lane 1),Hep G2 (Lane 2), BeWo (Lane 3), SH-SY5Y (Lane 4) and THP 1 (Lane 5); and tissue extracts of Mouse Thymus were electrophoresed using NuPAGE™ 10% Bis-Tris Protein Gel (Product # NP0301BOX). 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 (0.75 µg/mL) 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 SuperSignal™ West Dura Extended Duration Substrate (Product # 34076).

SQSTM1 Antibody in Knockdown — Antibody specificity was demonstrated by siRNA mediated knockdown of target protein. Hep G2 cells were transfected with SQSTM1 siRNA and decrease in signal intensity was observed in Western Blot application using Anti-SQSTM1 Polyclonal Antibody (Product # PA5-20839). {KD}

Target Information

This gene encodes a multifunctional protein that binds ubiquitin and regulates activation of the nuclear factor kappa-B signaling pathway. The protein functions as a scaffolding/adaptor protein in concert with TNF receptor-associated factor 6 to mediate activation of NF-kB in response to upstream signals. Alternatively spliced transcript variants encoding either the same or different isoforms have been identified for this gene. Mutations in this gene result in sporadic and familial Paget disease of bone.
