CD14 Monoclonal Antibody (61D3), Super Bright™ 600, eBioscience™, Invitrogen™

Description

• Description: The 61D3 monoclonal antibody reacts with human CD14, a 53-55 kDa GPI-linked glycoprotein
• CD14 is expressed on monocytes, interfollicular macrophages and some dendritic cells
• Complexes of LPS and LBP (LPS-Binding Protein) bind with high affinity to monocytes through the surface CD14
• Applications Reported: This 61D3 antibody has been reported for use in flow cytometric analysis
• Applications Tested: This 61D3 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells
• This can be used at 5 μL (0.5 μg) per test
• A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL
• Cell number should be determined empirically but can range from 10 5 to 10 8 cells/test
• Super Bright 600 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 600 nm
• We recommend using a 610/20 bandpass filter
• Please make sure that your instrument is capable of detecting this fluorochrome
• When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Staining Buffer (cat
• SB-4400) to minimize any non-specific polymer interactions
• Please refer to the datasheet for Super Bright Staining Buffer for more information
• Light sensitivity: This tandem dye is sensitive to photo-induced oxidation
• Protect this vial and stained samples from light
• CD14 is a 55 kDa GPI-anchored glycoprotein that is constitutively expressed on the surface of mature monocytes, macrophages, and neutrophils
• CD14 also serves as a multifunctional lipopolysaccharide receptor, and is released to the serum both as a secreted and enzymatically cleaved GPI-anchored form
• CD14 binds lipopolysaccharide molecule in a reaction catalyzed by lipopolysaccharide-binding protein (LBP), an acute phase serum protein
• The soluble sCD14 can discriminate slight structural differences between lipopolysaccharides and is important for neutralization of serum allochthonous lipopolysaccharides by reconstituted lipoprotein particles
• Further, CD14 has been shown to bind apoptotic cells, and can affect allergic, inflammatory and infectious processes
• Alternative splicing results in multiple transcript variants encoding the same CD14 isoform
• Diseases associated with CD14 dysfunction include mycobacterium chelonae infection and Croup.
