HSP40 Antibody in Immunocytochemistry (ICC/IF) — Immunofluorescence analysis of HSP40 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 1 hour at room temperature. The cells were labeled with HSP40 Rabbit Polyclonal Antibody (Product # PA5-76452) at 5 µg/mL in 0.1% BSA, incubated at 4 degree celsius overnight and then with Goat anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32731) at a dilution of 1:2000 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 cytoplasmic and nuclear localization. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

HSP40 Antibody in Western Blot (WB) — Western blot was performed using Anti-HSP40 Polyclonal Antibody (Product # PA5-76452) and a 40 kDa band corresponding to HSP40 was observed across cell lines and tissue extract tested. Whole cell extracts (30 µg lysate) of HeLa (Lane 1), U-87 MG (Lane 2), MCF-7 (Lane 3), Caco-2 (Lane 4), Hep G2 (Lane 5) and tissue extract of Mouse Testis (Lane 6) were electrophoresed using NuPAGE™ 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 the primary antibody (1:2000 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).

HSP40 Antibody — Antibody specificity was demonstrated by siRNA mediated knockdown of target protein. HeLa cells were transfected with HSP40 siRNA and decrease in signal intensity was observed in western blot application using HSP40 Polyclonal Antibody (Product # PA5-76452). {KD}

Target Information

TCF-9 (transcription factor 9), also known as C2orf3 (chromosome 2 open reading frame 3), GCF (GC-rich sequence DNA-binding factor) or DNABF, is a 781 amino acid nuclear protein that belongs to the GCF family. Widely expressed, GCF binds the GC-rich sequences of beta-Actin, EGFR and calcium-dependent protease (CANP) promoters. GCF contains multiple phosphoserine and phosphothreonine residues, and two GCF isoforms are produced due to alternative splicing events. GCF is considered a candidate for susceptibility to dyslexia (DYX3) as both genes reside in close proximity on human chromosome 2. Chromosome 2 is the second largest human chromosome and consists of 237 million bases, encodes over 1,400 genes and makes up approximately 8% of the human genome.
