Product Information
Product Description
This Cell Signaling Technology® F(ab’)2 fragment lacks an Fc domain, and will not exhibit reactivity with human Fc receptors. This eliminates the need for Fc blocking and reduces false positives in assays containing human monocytes or other cells with high expression of Fc receptors.
The F(ab')2 fragment is generated by enzymatic digestion of the full-length IgG clone coupled with chromatography to remove both the Fc fragment and the intact IgG. The F(ab’) fragment is conjugated to Alexa Fluor® 488 fluorescent dye under optimal conditions.

Background
Human Fc receptors exhibit strong cross-reactivity with rabbit IgG, and are expressed at high levels on cells of myeloid lineage (e.g., monocytes and myeloid-derived cell lines). Fluorescent anti-linker F(ab')2 fragment conjugates are ideal for use in flow cytometry assays on cells containing Fc receptors, and eliminate the need for an Fc blocking step prior to antibody incubation.
Cell Signaling Technology employs strict quality control procedures to ensure that each conjugate provides optimal specificity and fluorescence.
