Phosphate-buffered solution, pH 7.2, containing no preservative. 0.2 μm filter sterilized. Endotoxin level is < 0.1 EU/μg of the protein (< 0.01 ng/μg of the protein) as determined by the LAL test.
Preparation:
The LEAF™ (Low Endotoxin, Azide-Free) antibody was Purified by affinity chromatography.
Concentration:
1.0 mg/ml
Storage & Handling:
The antibody solution should be stored undiluted at 4 °C. This LEAF™ solution contains no preservative; handle under aseptic conditions.
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is ≤2.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes:
The M5E2 antibody inhibits monocyte activation and cytokine production induced by LPS. Additional reported applications (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen sections, blocking of LPS stimulation4, and immunofluorescence microscopy5. Clone M5E2 is not recommended for immunohistochemical staining of formalin-fixed paraffin-embedded sections. The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm sterile-filtered) is recommended for functional assays (Cat. No. 301810).

Human peripheral blood monocytes stained with LEAF™ purified M5E2, followed by anti-mouse IgG FITC
CD14 is a 53-55 kD glycosylphosphatidylinositol (GPI)-linked membrane glycoprotein also known as LPS receptor. CD14 is expressed at high levels on monocytes and macrophages, and at lower levels on granulocytes. Some dendritic cell populations such as interfollicular dendritic cells, reticular dendritic cells, and Langerhans cells have also been reported to express CD14. As a high-affinity receptor for LPS, CD14 is involved in the clearance of gram-negative pathogens and in the upregulation of adhesion molecules and cytokines expression in monocytes and neutrophils.
Other Names:

Structure:
GPI-linked membrane glycoprotein, 53-55 kD
Distribution:
Monocytes, macrophages, granulocytes (low)
