neuromab icon sm.png NeuroMab/Trimmer Lab Recombinant mAb Plasmid Collection

The UC Davis/NIH NeuroMab Facility together with the laboratory of NeuroMab Director, Dr. James Trimmer, have produced numerous monoclonal antibodies (NeuroMabs) extensively validated for neuroscience research applications. A substantial number of these have been cloned, expressed and validated in recombinant form. The recombinant monoclonal antibodies or R-mAbs have been engineered such that they are a distinct IgG subclass from the conventional mAb to facilitate multiplex labeling with subclass-specific secondary antibodies. The plasmids encoding these R-mAbs have been deposited with Addgene for distribution to the research community. Protocols for the generation R-mAbs plasmids, production of R-mAbs in transfected cells and their validation can be found below.

Schematic of antibody plasmid

With these plasmids researchers will be able to easily and inexpensively generate R-mAbs by transiently transfecting the plasmids into mammalian tissue culture cells (e.g., HEK293, COS, CHO), from which the R-mAbs are secreted into the culture media. For high level expression we recommend using the HEK-2936E cell line engineered by Durocher et al., 2002.

The schematic to the right shows the separate elements of the R-mAb expression plasmid involved in coexpression of light (green) and heavy (blue) chains as driven by two CMV promoters (orange). Hybridoma-derived VL and VH domain PCR products are fused to a joining fragment comprising a κ light chain constant domain (CL) and the κ light chain polyA tail sequences (κ pA), a CMV promoter for heavy chain expression, and an ER signal/leader sequence (L) for translocation of the heavy chain across the ER membrane. PCR-mediated fusion of these three elements is followed by their insertion into the p1316 plasmid that contains an upstream CMV promoter for light chain expression, and an ER signal/leader sequence (L) for translocation of the light chain across the ER membrane. Downstream of the insert is a heavy chain constant domain (CH) that is either γ1 or γ2a depending on the plasmid, followed by the SV40 polyA tail (SV40 pA).
