Provider: Invitrogen Antibodies
Product name: CD68 Monoclonal Antibody (KP1), eBioscience™
Antibody type: Monoclonal
Antigen: Other
Description: Description: The KP1 antibody reacts with human CD68 which belongs to the sialomucin family and is closely related to the family of lysosomal-associated membrane proteins (lamps) and scavenger receptor. CD68 is predominantly an intracellular protein, found mainly in the late endosomal compartment but can be detected in smaller amounts on the surface of mainly myeloid-derived cells; monocytes and macrophages, dendritic cells (and in some langerhan cells), neutrophils, basophils, mast cells, myeloid progenitor cells, and a subset of CD34+ hematopoietic bone marrow progenitor cells. The function has not been fully elucidated but based on homology and structure, CD68 may play a role in antigen processing or presentation and protection of the lysosomal membrane from hydrolytic enzymes. Reports have also shown expression in activated T cells, and about 40% of peripheral blood B-lymphocytes and 50% of all B-ALL. The KP1 antibody has also been reported to stain fibroblasts which may be due to a conserved epitope rather than fibroblasts expressing CD68.
Antibody clone number: KP1

Experimental details: Immunohistochemical analysis of CD68 was performed using formalin-fixed paraffin-embedded human tonsil tissue sections. To expose the target protein, heat-induced epitope retrieval was performed on de-paraffinized sections using eBioscience™ IHC Antigen Retrieval Solution - High pH (10X) (Product # 00-4956-58) diluted to 1X solution in water in a microwave oven at 100 degree Celsius for 15 minutes. Following antigen retrieval, the sections were blocked with 2% normal goat serum in 1X PBS for 45 minutes at room temperature and then probed with or without CD68 Monoclonal Antibody (KP1), eBioscience™ (Product #14-0688-82) at 5 µg/mL in 0.1% normal goat serum overnight at 4 degree Celsius in a humidified chamber. Detection was performed using Goat anti-Mouse IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor Plus 488 (Product # A32723) at a dilution of 1:2000 in 0.1% normal goat serum for 45 minutes at room temperature. ReadyProbes™ Tissue Autofluorescence Quenching Kit (Product # R37630) was used to quench autofluorescence from the tissues. Nuclei were stained with DAPI (Product # D1306) and the sections were mounted using ProLong™ Glass Antifade Mountant (Product # P36984). The images were captured on EVOS™ M7000 Imaging System (Product # AMF7000) at 20X magnification and externally deconvoluted.
