CD68 Antibody

SKU: orb2642410

Description

This antibody recognizes a glycoprotein of 110kDa, which is identified as CD68. It is important for identifying macrophages in tissue sections. It stains macrophages in a wide variety of human tissues, including Kupffer cells and macrophages in the red pulp of the spleen, in lamina propria of the gut, in lung alveoli, and in bone marrow. It reacts with myeloid precursors and peripheral blood granulocytes. It also reacts with plasmacytoid T cells, which are supposed to be of monocyte/macrophage origin. It shows strong granular cytoplasmic staining of chronic and acute myeloid leukemia and also reacts with rare cases of true histiocytic neoplasia. Lymphomas are negative or show few granules.

Immunology & Inflammation

Images & Validation

• Tested Applications: IHC-P
• Dilution Range: Immunohistochemistry (FFPE): 0.25-0.5ug/ml for 30 min at RT
• Reactivity: Human
• Application Notes:
  Optimal dilution of the CD68 antibody should be determined by the researcher.1. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

IHC staining of FFPE human tonsil with CD68 antibody (clone C68/2709). HIER: boil tissue sections in pH6 10 mM citrate buffer, or pH9 10 mM Tris with 1 mM EDTA, for 10-20 min followed by cooling at RT for 20 min.

Analysis of HuProt (TM) microarray containing more than 19000 full-length human proteins using CD68 antibody (clone C68/2709). These results demonstrate the foremost specificity of the C68/2709 mAb. Z- and S- score: The Z-score represents the strength of a signal that an antibody (in combination with a fluorescently-tagged anti-IgG secondary Ab) produces when binding to a particular protein on the HuProt (TM) array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If the targets on the HuProt (TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-scores. The S-score therefore represents the relative target specificity of an Ab to its intended target.
