Additional Information

Alternative name: CD14

Immunogen: A crude mixture of human urinary proteins precipitated by ammonium sulphate from theurine of a patient suffering from proteinuria.

Isotype: IgG1

Clone: MEM-18

Description: CD14 is a 55 kDa GPI-anchored glycoprotein, constitutively expressed on the surface ofmature monocytes, macrophages, and neutrophils, where serves as a multifunctionallipopolysaccharide receptor, it is also released to the serum both as a secreted andenzymatically cleaved GPI-anchored form. CD14 binds lipopolysaccharide molecule in areaction catalyzed by lipopolysaccharide-binding protein (LBP), an acute phase serumprotein. The soluble sCD14 is able to discriminate slight structural differences betweenlipopolysaccharides and is important for neutralization of serum allochthonouslipopolysaccharides by reconstituted lipoprotein particles. CD14 affects allergic,inflammatory and infectious processes.

Specificity: The antibody MEM-18 reacts with CD14, a 53-55 kDa GPI(glycosylphosphatidylinositol)-linked membrane glycoprotein expressed on monocytes,macrophages and weakly on granulocytes, also expressed by most tissue macrophages. Inhuman, the epitope recognized by MEM-18 is located between amino acids 57-64.HLDA III, WS Code M 253HLDA IV, WS Code M 314HLDA V, WS Code M MA087HLDA VI, WS Code M MA95
