Clone: HIM3-4.
Conjugate: FITC.
Immunogen: CD33-Fc recombinant protein.
Storage Buffer: The reagent is provided in aqueous buffered solution containing protein stabilizer, and ≤0.09% sodium azide (NaN3).
Recommended Usage: CD33, clone HIM3-4 is a mAb intended for the identification/enumeration of Siglec-3 using FCM. This reagent is effective for direct IF staining of human tissue for FCM analysis using ≤1 μg/106 cells.
CD33 is a 67 kD type I transmembrane glycoprotein also known as Siglec-3, gp67, and p67. It is a sialoadhesion immunoglobulin superfamily member expressed on myeloid progenitors, monocytes, granulocytes, dendritic cells and mast cells. CD33 is absent on normal platelets, lymphocytes, erythrocytes and hematopoietic stem cells. CD33 functions as a sialic acid-dependent cell adhesion molecule with carbohydrate/lectin binding activity.
