Product Specifications

Immunogen

Gemtuzumab was generated by huminization of the murine P67.6 clone, raised against CD33-transfected FMY9S5 cells of human origin. CD33 is a transmembrane receptor expressed on predominantly on cells of the myeloid lineage, but it can also be found on some lymphoid cells.

Specificity

Recognises human CD33.

Clonality

Monoclonal

Host

Human

Isotype

IgG4 kappa

Flow Cytometry

Optimal dilutions of this antibody should be experimentally determined.
Application Notes
Optimal dilution of this antibody should be experimentally determined. For optimal results using our Tandem dyes, please avoid prolonged exposure to light or extreme temperature fluctuations. These can lead to irreversible degradation or decoupling. When staining intracellular targets, specific attention to the fixation and permeabilization steps in your flow protocol may be required.

Background: Siglec-3/CD33

CD33 is a 67 kDa type I transmembrane glycoprotein and a member of the sialoadhesin family of cell surface receptors. It is absent from pluripotent stem cells but appears on myelomonocytic precursors after CD34. It then continues to be expressed on both the myeloid and monocyte lineages, although it is absent on granulocytes. While it has been reported that CD33 can function as a sialic acid-dependent cell adhesion molecule, cells expressing CD33 require desialylation before they can bind cells bearing the appropriate sialoglycoconjugates. This suggests that inhibitory cis interactions may regulate or block any adhesion function. (1-4)

Long Name

Sialic Acid Binding Ig-like Lectin 3
