CD14 (cluster of differentiation 14), also known as CD14, is a human gene. The protein encoded by this gene is a component of the innate immune system. CD14 exists in two forms, one anchored to the membrane by a glycosylphosphatidylinositol tail (mCD14), the other a soluble form (sCD14). Soluble CD14 either appears after shedding of mCD14 (48 kDa) or is directly secreted from intracellular vesicles (56 kDa). CD14 is an acute phase glycoprotein that binds lipopolysaccharide endotoxins (LPS) from Gram-negative bacteria. It is primarily expressed on monocytes, macrophages, and neutrophils, and soluble forms can be secreted or shed from the cell surface. CD14 accepts LPS from its initial binding by LBP, and it can further transfer LPS to the TLR4/MD2 complex. LPS acctivation of TLR4 triggers inflammatory activation. CD14 also contributes to the response to TLR3 ligands, phosphoinositides, as well as the surfactant proteins SP-A and SP-D.
The entire kit may be stored at -20°C for up to 1 year from the date of shipment. Avoid repeated freeze-thaw cycles. The kit may be stored at 4°C for up to 6 months. For extended storage, it is recommended to store at -80°C.
Human CD14 ELISA Kit is for Research Use Only.
