Description

The WM-53 monoclonal antibody reacts with human CD33, also known as GP67 and P67, a 67 kDa type I transmembrane glycoprotein that is a member of the Siglec (sialic acid-binding Ig superfamily lectin) family. It is highly specific to the hematopoietic compartment and is expressed on monocytes, activated T cells, granulocytes, myeloid progenitors, and mast cells.

Applications Reported

For research use only, not for diagnostic or therapeutic use. This WM-53 (WM53) antibody has been reported for use in flow cytometric analysis.

The Alexa Fluor® 700 emits at 723 nm and can be excited with the He-Ne 633 laser. Most instruments will require a 685 LP mirror and 710/20 filter. Please make sure that your instrument is capable of detecting this fluorochome.

Applications Tested

This WM-53 (WM53) antibody has been pre-titrated and tested by flow cytometric analysis of lysed whole blood. This can be used at 20 μl (0.5 μg) per 100 μl blood (or per 1 million cells in 100 μl total staining volume).
