Description
PA007397: Recombinant Mouse IgG2a Isotype Control Antibody
The recombinant anti-HEL mouse IgG2a isotype control antibody binds to neither human nor mouse samples.
Background of Recombinant Mouse IgG2a Isotype Control Antibody
Recombinant mouse IgG isotype control antibodies help minimize non-specific binding of primary and capture antibodies by blocking interactions between antibody Fc fragments and Fc receptors, and preventing non-specific antibody binding to cellular proteins, carbohydrates, and lipids. Normal mouse serum and purified mouse IgGs from normal mouse serum are commonly used as non-specific passive blocking solution for antibody-based immuno-assays. Recombinant mouse IgG antibody mixes, as a direct alternative to normal mouse serum and even mouse IgGs purified from mouse serum or a non-specific passive blocking solution, can be used to eliminate interfering antibodies from immuno-assay systems using capture and detection antibodies. There is higher percentage of mouse IgG1 or IgG2b in serum from different strains of mice.
Features of recombinant mouse IgG isotype control antibodies compared with normal mouse serum and serum-derived mouse IgGs:
1) Animal free production. CHO cells rather than mice are used in antibody production.
2) Lot-to-lot consistency. CHO cells which are used for antibody drug manufacturing are used to manufacture the mouse IgG isotype control antibodies in the antibody mixes. All production is under control and predictable.
3) As a targeted or passive antibody blocker to interfering antibodies like HAMA (Human Anti-Mouse Antibodies) and no binding to human tissues. In contrast, some serum-derived mouse IgGs may bind to unknown targets in some human tissues.
4) Adjustable percentages of the recombinant mouse IgG isotype control antibodies in the recombinant mouse IgG antibody mixes. A customized recombinant mouse IgG antibody mix with different percentages of mouse IgG1, IgG2a, IgG2b, IgG2c, and IgG3 isotype control antibodies can be easily made according to customers’ applications.
Recombinant mouse IgG isotype control antibodies are the best normal mouse serum alternative as blocking reagents, and serum-derived mouse IgGs alternative.
The most popular human Fc blocking reagents include:
Anti-human CD16 (clone 3G8), and CD32 (Clone IV.3): for flow cytometry, immunohistochemistry (IHC), and immunoprecipitation (IP). It is highly specific for FcγRII (CD32) and FcγRIII (CD16), and reduces background staining; it may not block all Fc receptors. Clones 10.1, and 22 or H22 are the most widely used anti-human FcγRI (CD64) clone for Fc blocking in flow cytometry and functional assays. It prevents non-specific Fc receptor binding on monocytes, macrophages, and dendritic cells, improving antibody specificity.
Purified human IgGs or mixes of human isotype controls: for general Fc blocking in IHC and immunofluorescence (IF). It is cheap and easy to use but it is less specific, and may even introduce unwanted immunoglobulins. Syd Labs supply various human IgG isotype controls.
Normal mouse serum, purified mouse IgG or isotype controls: for flow cytometry. It can serve as a control to block Fc receptors but it is non-specific for Fc receptors. It is cheap and easy to use but it is less specific, and may even introduce unwanted immunoglobulins. Our recombinant mouse IgG antibody mixes are affordable; the ratio of various IgGs is optimized and adjustable without any unwanted immunoglobulins.
Bovine Serum Albumin (BSA) or FBS: for general blocking in Western Blot (WB) and IHC. They are readily available to reduce non-specific binding but less effective at Fc receptor blocking.
Commercial Fc blocking solutions: for flow cytometry, IHC, and functional assays. They are normally pre-optimized and highly effective but more expensive than DIY solutions.
Best choice of human Fc blocking reagents based on your application are:
For flow cytometry: anti-human CD16 (Clone 3G8), CD32 (Clone IV.3), and CD64 (Clone 10.1, and 22 or H22).
For Immunohistochemistry (IHC) and Immunofluorescence (IF): Normal mouse serum, purified mouse or human IgGs or isotype controls or commercial Fc blocking kits. Our recombinant mouse IgG antibody mixes and recombinant human IgG isotype controls are affordable; the ratio of various IgGs is optimized and adjustable without any unwanted immunoglobulins.
For Western Blot and ELISA: BSA or FBS.
For functional assays (e.g., blocking Fc-mediated effects): Commercial Fc blocking reagents.
