Description

This antibody is predicted to react with Monkey, Rat, Sheep, Pig, Bovine Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems. The expression systems are developed by cloning in the specific antibody DNA sequences from immunoreactive rabbits. Then, individual clones are screened to select the best candidates for production. The advantages of using recombinant rabbit monoclonal antibodies include: better specificity and sensitivity, lot-to-lot consistency, animal origin-free formulations, and broader immunoreactivity to diverse targets due to larger rabbit immune repertoire.

Experimental details

Western blot analysis was performed on Whole cell extracts (30 µg lysate) of HeLa (Lane 1), Jurkat (Lane 2), MCF-7 (Lane 3), Raji (Lane 4), Hep G2 (Lane 5), C2C12 (Lane 6), Caco-2 (Lane 7) and PC-3 (Lane 8). The blots were probed with Anti-DDX48 (elF4A3) Recombinant Rabbit Monoclonal Antibody (Product # 702545, 1-2 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (Heavy Chain) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:2500 dilution). A 47 kDa band corresponding to DDX48 (elF4A3) was observed across the cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12% Bis-Tris gel (Product # NP0321BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5% skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western blotting Substrate (Product # 32106).

Experimental details

For immunofluorescence analysis, HeLa cells were fixed and permeabilized for detection of endogenous eIF4A3 using Anti-eIF4A3 Recombinant Rabbit Monoclonal Antibody (Product # 702545, 2 µg/mL) and labeled with Goat anti-Rabbit IgG (Heavy Chain) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Panel a) shows representative cells that were stained for detection and localization of eIF4A3 protein (green), Panel b) is stained for nuclei (blue) using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). Panel c) represents cytoskeletal F-actin staining using Rhodamine Phalloidin (Product # R415, 1:300). Panel d) is a composite image of Panels a, b and c clearly demonstrating cytoplasmic and nuclear localisation of eIF4A3. Panel e) represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.
