Applications: 1. Useful for screening or performing binding assays of antibodies designed against human CD14 in a cellular context.
2. Cell-based assays for the assessment of CD14-mediated cell signaling and/or genetic responses under various experimental conditions (eg. inhibition/neutralization or activation/amplification).
Background: CD14 (Cluster of Differentiation-14) is a surface antigen expressed predominantly by monocytes & macrophages. It is considered a patterned recognition receptor (PRR), which recognizes pathogen markers. Specifically, CD14 acts as a co-receptor for lipopolysaccharides (LPS) found in the outer membrane of gram-negative bacteria. Through this interaction, CD14 supports initiation of the innate immune response during bacterial infection. CD14 has also been found to contribute toward immune responses to viral pathogens such as human respiratory syncytial virus (RSV), and may amplify the inflammatory response observed in severe cases of SARS-CoV-2 infection (COVID-19). Monoclonal antibodies against CD14 are currently undergoing clinical trial as a candidate treatment to limit severe inflammatory responses common in patients hospitalized with COVID-19
Description: Recombinant clonal CHO stable cell line constitutively expressing full length human CD14 protein. The surface expression of CD14 in this cell line was validated by flow cytometry.
Host Cell Line: CHO
Mycoplasma Testing: The cell line has been screened using the MycoAlert™ Mycoplasma Detection kit (Lonza, #LT07-218) to confirm the absence of Mycoplasma species.
Storage Stability: Cells will arrive upon dry ice and should immediately be thawed or stored in liquid nitrogen upon receipt. Do not use a -80°C freezer for long term storage.
Supplied As: Each vial contains 2 x 106 cells in 1 ml of 10% DMSO in FBS
Warnings: Avoid freeze/thaw cycles.
Biosafety Level: BSL-1
