CD68 (PG-M1) Macrophages, human


Catalogue number: CD68-5

ClonePG-M1
IsotypeIgG3, k
Units5 ml
HostMouse
Application IHC(C
P)
Background
The antibody PG-M1 is well suited for the detection of tissue macrophages including Kupffer cells and spleen macrophages. Among a number of CD68 antibodies PG-M1 is one of the most specific ones, since it stains neither myeloid precursor cells, nor granulocytes or dendritic cells. In acute myeloid leukaemia (AML) types M4 and M5 will be stained, while M1 - M3, M6 and M7 remain unstained. CD68 is a transmembrane antigen, which is localised mainly in lysosomes. It belongs to the family of LAMP glycoproteins, which are involved in lysosomal transport and endocytosis respectively. The exact function of the CD68 molecule is not known. CD68 transmembran glycoprotein MW 110 kDa, localised in macrophages.

Positive Control
Tonsil, spleen

Pre-Treatment
Heat pre-treatment of formalin-fixed tissue with Unmasking Fluid C, E or G (Art. No. DE000, DE006, and DE007). Unmasking with Pronase (Art. No. DE110) or Proteinase K is also suitable.

Immunogen
Gaucher cells

Purification Method
Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide**. The volume is sufficient for at least 50 immunohistochemical tests (100 µl working solution / test). Use appropriate antibody diluent e.g. BIOLOGO Art. No. PU002, if further dilution is required.

Working Concentration
(RTU) neat

Incubation Time
60 min at RT

Secondary Reagents
We recommend the use of BIOLOGO's Universal Staining System DAB (Art. No. DA005) or AEC (Art.-No. AE005).

Caution
*These antibodies are intended for in vitro research use only. They must not be used for clinical diagnostics and not for in vivo experiments in humans or animals. ** The preservative sodium azide is known to be poisonous and potentially hazardous to health. It should be handled only by trained staff. Despite of the product's low azide concentration it must be handled with care. Dispose according to regional rules!
