Description

Human Fc receptors (FcRs) are expressed on a variety of cells, such as monocytes, granulocytes, B cells and dendritic cells. The cells with FcR expression sometimes give false positive or false negative results of immunofluorescent staining due to the FcRs-mediated Ig Fc binding. Human TruStain FcX™ is specially formulated for blocking the FcR-involved unwanted staining without interfering with antibody-mediated specific staining of human cells. Human TruStain FcX™ is compatible with flow cytometric staining with anti-human CD16 (clone 3G8), CD32 (clone FUN-2), and CD64 (clone 10.1) antibodies.

Storage & Handling
Store between 2°C and 8°C.
Application

FC - Quality tested
ICFC, ICC - Reported in the literature, not verified in house

Recommended Usage

It is recommended to add 5 µl of Human TruStain FcX™ per million cells in 100 µl staining volume, mix and incubate at room temperature for 5-10 minutes prior to staining with antibody of interest. It is not necessary to wash cells between these blocking and immunostaining steps.

Application Notes

This buffer contains specialized human IgG in PBS containing 0.09% sodium azide. It is not recommended to be used for staining human IgG. Handle as biohazard agent.
