HSP40 Antibody in Immunocytochemistry (ICC/IF) — Immunofluorescence analysis of HSP40 was performed using 70% confluent log phase HeLa cells heat shocked at 43°C for 1 hr. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 15 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with HSP40 Polyclonal Antibody (Product # PA5-17382) at 1:400 dilution in 0.1% BSA, incubated at 4 degree Celsius overnight and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) 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 nuclear translocation upon heat shock. Panel e shows untreated HeLa cells with cytoplasmic localization. Panel f represents control cells with no primary to assess background. The images were captured at 60X magnification.

HSP40 Antibody in Western Blot (WB) — Knockdown of HSP40 was achieved by transfecting HeLa cells with HSP40 specific siRNAs (Silencer® select Product # s7009, s223882). Western blot analysis (Fig. a) was performed using whole cell extracts from the HSP40 knockdown cells (lane 3), non-specific scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The blot was probed with HSP40 Polyclonal Antibody (Product # PA5-17382, 1:2000 dilution) and Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.25µg/ml, 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 HSP40.

HSP40 Antibody — Antibody specificity was demonstrated by siRNA mediated knockdown of target protein. HeLa cells were transfected with HSP40 specific siRNA and decrease of signal was observed in Western Blot using Anti-HSP40 Polyclonal Antibody (Product # PA5-17382). {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.
