Flow cytometry analysis of F(ab')2-Goat anti-Rabbit IgG (H+L) Cross-Adsorbed Secondary Antibody, APC (31984) was performed using K-562 cells stained with Laminin-211 Rabbit Oligoclonal Antibody (711233). Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with Laminin-211 antibody or with rabbit isotype control at 3-5 ug/million cells in 2.5% BSA and incubated for 2 hours at room temperature. The cells were then labeled with F(ab')2-Goat anti-Rabbit IgG (H+L) Cross-Adsorbed Secondary Antibody, APC (31984) at a dilution of 1:500 for 1 hour at room temperature. A representative 10,000 cells were acquired and analyzed for each sample using the Attune® NxT Acoustic Focusing Cytometer. Panels a, b and c represent cells stained with the secondary antibody alone, isotype control and Laminin-211 oligoclonal antibody respectively. Median fluorescence intensity from the three samples is compared in panel d.

Product # 31984 has been successfully used in Western blot, IF, ICC, IHC, IP and FACS applications.
Product # 31984 reacts with the heavy chains of rabbit IgG and with the light chains common to most rabbit immunoglobulins, but does not react against non-immunoglobulin serum proteins. This antibody has been tested by ELISA and/or solid-phase adsorbed to ensure minimal cross-reaction with human, mouse, and rat serum proteins. However, this antibody may cross-react with immunoglobulins from other species.
Phycobiliprotein Concentration: 0.5 mg/ml (determined by absorption = 73 at 650 nm for a
1% solution for only those APC molecules to which at least one molecule of active antibody is bound)

Thermo Scientific 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.
