• Target description: Monocyte differentiation antigen CD14 (UniProt: P08571; also known as Myeloid cell-specific leucine-rich glycoprotein, CD14) is encoded by the CD14 gene (Gene ID: 929) in human. CD14 is a GPI-anchor membrane glycoprotein that serves as a co-receptor for several Toll-like receptors. Together with TLR4 and MD-2, it forms the multi-receptor complex that recognizes Lipopolysaccharide (LPS) on the cell membrane. In the presence of LPS, CD14 and TLR4-MD2 are brought into close proximity inside lipid rafts and after translocation into the lipid rafts, TLR4 in the plasma membrane activates the TIRAP-MyD88-dependent pathway that leads to the first wave of NF-B activation. CD14 also acts as a co-receptor for TLR2:TLR6 heterodimer in response to diacylated lipopeptides and for TLR2:TLR1 heterodimer in response to triacylated lipopeptides. These clusters trigger signaling from the cell surface and subsequently are targeted to the Golgi in a lipid-raft dependent pathway. CD14 expression has been reported on cells of both hematopoietic and non-hematopoietic origin. A secreted form of CD14 has also reported that arises from the cleavage of the GPI anchor. CD14 is expressed on macrophages and a strong expression has been reported on the surface of monocytes. Its expression on monocytes is induced by 27-hydroxycholesterol that primes monocytes/macrophages to accelerate LPS-mediated inflammatory reaction. CD14-deficient macrophages display a significantly reduced sensitivity to low concentrations of LPS compared to wild-type cells and CD14 deficient mice do not develop septic shock after exposure to LPS or Gram-negative bacteria. CD14 is synthesized with a signal peptide (aa 1-19) and a propeptide (aa 346-375) that are cleaved off to generate the mature form. The mature form contains 11 leucine-rich repeats (LRR) that are required for responses to smooth LPS. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
• Reconstitution: 30 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
• Storage and Stability: Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
