Mouse Seroblock FcR | FCR4G8
Mouse Seroblock FcR is a rat antibody that recognises mouse CD16 and CD32, cell surface proteins also known as FcRγIII and FcR&gamma:II, respectively. The function of these proteins is to bind IgG molecules via their Fc regions as part of the adaptive immune response. CD16 and/or CD32 are expressed by a wide variety of cells, including monocytes, macrophages, B lymphocytes, granulocytes, NK cells, dendritic cells and some activated T lymphocytes. The expression of CD16/CD32 antigens can lead to non-specific binding of test monoclonal antibodies in staining procedures, resulting in “high background” staining on a wide range of cells. This non-specific binding may be blocked by pre-incubation of target cells with BUF041A, resulting in clearer staining. For direct analysis of CD16/32 expression this antibody is also available conjugated directly to FITC (MCA2305F ), AlexaFluor488 (MCA2305A488), AlexaFluor647 (MCA2305A647 ) and RPE (MCA2305PE ).

Applications of Mouse Seroblock FcR
|Application Name||Verified||Min Dilution||Max Dilution|
Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
- Instructions For Use
- In order to reduce Fc-receptor mediated binding of test antibodies the following procedure is recommended:-
1) Incubate the cell suspension (1 x 106 cells in 100ul) with 1ug of BUF041A (1ul of undiluted reagent, or 10ul of a 1/10 dilution) for 5-10 minutes.
2) Add test antibody according to manufacturers instructions – Do not wash BUF041A off the cells. BUF041A is suitable for use in conjunction with test antibodies from any manufacturer or with in-house antibodies.*
3) Proceed with staining as usual.
* Care is needed in the design of experiments utilizing unconjugated anti-mouse antibodies, to ensure that the secondary antibody being used does not cross-react with SeroBlock FcR. Bio-Rad supply a range of isotype specific anti-mouse immunoglobulin antibodies that may be useful for this purpose.
