DDX5 Antibody (PA1-31019) in WB

Western blot was performed using Anti-DDX5 Polyclonal Antibody (Product # PA1-31019) and a 60 kDa band corresponding to DDX5 was observed across cell lines and tissues tested. Modified whole cell extracts (1% SDS) (30 µg lysate) of HeLa (Lane 1), SH-SY5Y (Lane 2),Hep G2 (Lane 3), MCF7 (Lane 4), HT-29 (Lane 5), NIH/3T3 (Lane 6) and Rat testis (Lane 7) were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry ... View More

DDX5 Antibody in Immunocytochemistry (ICC/IF) — Immunofluorescence analysis of DDX5 was performed using 70% confluent log phase MCF7 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 DDX5 Polyclonal Antibody (Product # PA1-31019) at 1:100 dilution in 0.1% BSA, incubated at 4 degree Celsius overnight and then labeled with Rabbit anti-Goat IgG (H+L) Recombinant Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A-11078) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). F-actin (Panel c: red) was stained with Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing localization to the nucleus. Panel e represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

DDX5 Antibody in Immunohistochemistry (Paraffin) (IHC (P)) — Immunohistochemistry (Paraffin) analysis of DDX5 in human prostate tissue using DDX5 Polyclonal Antibody (Product # PA1-31019) at a dilution of 2.5 µg/mL. Antigen retrieval : citrate buffer pH 6.

DDX5 Antibody in RNA Immunoprecipitation (RIP) — RNA Immunoprecipitation (RIP) assay of endogenous DDX5 protein using Anti-DDX5 Antibody: RIP assay was performed using Anti-DDX5 Polyclonal Antibody (Product # PA1-31019, 5 ug) on whole cell lysate from HeLa cells. Normal IgG was used as a negative IP control. RNA purified by RiboPure™ RNA Purification Kit (Product # AM1924) was analyzed by RT-PCR using the Power SYBR® Green RNA-to-CT™ 1-Step Kit (Product # 4389986) with the primers pairs over U1 snRNA, ACTB, MALAT non-coding RNA and 5S rRNA. Data is presented as fold enrichment of the antibody signal versus the negative control IgG using the comparative CT method.

DDX5 Antibody — Antibody specificity was demonstrated by siRNA mediated knockdown of target protein. HeLa cells were transfected with DDX5 siRNA and decrease in signal intensity was observed in western blot application using DDX5 Polyclonal Antibody (Product # PA1-31019). {KD}

Target Information

DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases. They are implicated in a number of cellular processes involving alteration of RNA secondary structure, such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly. Based on their distribution patterns, some members of this family are believed to be involved in embryogenesis, spermatogenesis, and cellular growth and division. This gene encodes a DEAD box protein, which is a RNA-dependent ATPase, and also a proliferation-associated nuclear antigen, specifically reacting with the simian virus 40 tumor antigen. This gene consists of 13 exons, and alternatively spliced transcripts containing several intron sequences have been detected, but no isoforms encoded by these transcripts have been identified.
