Rabbit anti-Sheep IgG (H+L) Secondary Antibody, Invitrogen™

Description

Concentration may vary slightly from lot-to-lot, see lot-specific datasheet for exact concentration. Product # 31240 has been successfully used in Western blot, IF, ICC, IHC, IP and FACS applications. Product # 31240 reacts with the heavy chains of sheep IgG and with the light chains common to most sheep immunoglobulins, but does not react against non-immunoglobulin serum proteins. However, this antibody may cross-react with immunoglobulins from other species. Store product at 4°C until opened. 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. NOTE: For blocking, we recommend using a 4-5 % normal serum from the same host species of the labeled secondary antibody. The use of BSA and/or dry milk to block or dilute anti-bovine IgG, anti-goat IgG, anti-horse IgG, anti-sheep IgG and/or primary antibodies, may significantly increase background and/or reduce secondary antibody titer since BSA and dry milk may contain IgG which reacts with these antibodies.

Anti-Sheep secondary antibodies are affinity-purified antibodies with well-characterized specificity for ovine (sheep) 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.
