Product Information
Product Description
This Cell Signaling Technology® antibody is conjugated to Alexa Fluor® 532 fluorescent dye under optimal conditions and formulated at 200 µg/mL. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated #12698
Product Usage Information
SignalFlex™ conjugates are produced using highly validated Cell Signaling Technology® primary antibodies and conjugation methods that have been rigorously tested, ensuring high-quality conjugates and lot-to-lot consistency. These conjugates are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. However, they are not tested on specific assays.
Optimal dilutions/concentrations should be determined by the end user. When performing flow cytometry, we recommend using an isotype control conjugate at the same concentration as the antibody conjugate.

Background
A variety of plasmids contain DNA that encodes an amino-terminal tag consisting of six histidine (6xHis) residues followed by an extended multiple cloning site. The 6xHis tag on the expressed recombinant proteins allows for efficient coupling to Ni2+ affinity resins and purification by single step chromatography (1).
As is the case with other protein tag systems (2), this polyhistidine tag can often be cleaved at sites recognized by proteases such as thrombin and enterokinases to isolate the protein of interest (1).
