Western blot analysis of a FLAG Tag monoclonal antibody was performed by loading 50, 25, 12.5, 6.25, 3.25, and 1.5 ng of recombinant N-terminal FLAG-tagged ubiquitin protein and 10ul of PageRuler Plus Prestained Protein Ladder (Product # 26619) onto a 4-20% Tris-HCl polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked with StartingBlock T20 (TBS) Blocking Buffer (Product # 37543) for at least 1 hour. The membrane was probed with a FLAG Tag monoclonal antibody (Product # MA1-142) at a dilution of 1:1000 overnight at 4°C on a rocking platform, washed in TBS-0.1%Tween-20, and probed with a pre-diluted (0.8mg/ml) HRP-conjugated goat anti-rat IgG secondary antibody (Product # 31470) at a dilution of 1:10000 for 1 hour. Chemiluminescent detection was performed using SuperSignal West Pico (Product # 34080).

This antibody has been successfully used in Western blot, IF, ICC, IHC, IP and FACS applications.
Antibody Specificity: This antibody reacts with the heavy chains of rat IgG and with the light chains common to most rat immunoglobulins, based on immunoelectrophoresis. No antibody was detected against non-immunoglobulin serum proteins. However, this antibody may cross-react with immunoglobulins from other species.
Restoration and Storage: Store product at 4°C until opened. Restore with 2.0 ml distilled water (0.8 mg/ml after restoration). Centrifuge product if it is not completely clear after standing for 1-2 hours at room temperature. To judge clarity, draw product into a pasteur pipette. Product may be stored for several weeks at 4°C as an undiluted liquid. After dilution, do not use for more than one day.
To extend the shelf-life of this product, add an equal volume of glycerol to make a final concentration of approximately 50% glycerol and store at -20°C.

Thermo Scientific Anti-Rat secondary antibodies are affinity-purified antibodies with well-characterized specificity for rat 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.
