Western blot analysis was performed on nuclear enriched extracts (30 µg lysate) of HeLa (Lane 1) and U-87 MG (Lane 2). The blots were probed with ABfinity™ Anti-JUNB Recombinant Rabbit Monoclonal Antibody (Product # 701702, 2 µg/ml) and detected by chemiluminescence using Sheep anti-Rabbit IgG (H+L) Secondary Antibody, HRP (Product # A16172) at dilutions 1:2,000 (Fig. 1), 1:5,000 (Fig. 2) and 1:10,000 (Fig. 3). A 42 kDa band corresponding to JUNB was observed. Known quantity of protein samples were electrophoresed using Novex® NuPAGE®12 % Bis-Tris gel (Product # NP0342BOX), 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® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary antibody after blocking with 5 % skimmed milk. Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

The sensitivity of each lot of antibody is confirmed using ELISA. The specificity of each lot of antibody is confirmed by isoelectric focusing (IEF).
Anti-Rabbit secondary antibodies are affinity-purified antibodies with well-characterized specificity for rabbit immunoglobulins and are useful in the detection, sorting or purification of its specified target. Secondary antibodies offer increased versatility enabling users to use many detection systems (e.g. HRP, AP, fluorescence). They can also provide greater sensitivity through signal amplification as multiple secondary antibodies can bind to a single primary antibody. Most commonly, secondary antibodies are generated by immunizing the host animal with a pooled population of immunoglobulins from the target species and can be further purified and modified (i.e. immunoaffinity chromatography, antibody fragmentation, label conjugation, etc.) to generate highly specific reagents.
