Recombinant monoclonal antibodies for studying mitosis

At a Glance

Researchers at Colorado State University have developed a series of DNA plasmids and protocols for generating and purifying recombinant antibodies from HEY293 cells. This protocol can produce high-yield recombinant monoclonal antibodies at a relatively low cost. 

Follow each link to find more details about each product.

Overview

pDL026_HA-rb_IgG_LC_15F11 Info/Purchase

HA-tag light chain hypervariable regions grafted into 15F11 scaffold (Zhao et al., 2019) + rabbit light chain constant regions + exogenous N-term signal peptide. For co-expression with pDL025

pDL025_HA-rb_IgG_HC_15F11 Info/Purchase

HA-tag heavy chain hypervariable regions grafted into 15F11 scaffold (Zhao et al., 2019) + rabbit heavy chain constant regions + exogenous N-term signal peptide. For co-expression with pDL026.

pDL024_Tub-rb_IgG_LC Info/Purchase

α-Tubulin light chain variable region + rabbit light chain constant region + exogenous N-term signal peptide. For co-expression with pDL023 in HEK293 cells.

pDL023_Tub-rb_IgG_HC Info/Purchase

α-Tubulin heavy chain variable region + rabbit heavy chain constant regions + exogenous N-term signal peptide. For co-expression with pDL024 in HEK293 cells.

pDL002_Hec1-ms_IgG_LC Info/Purchase

Hec1 light chain variable and constant region (mouse) + exogenous N-term signal peptide. For co-expression with pDL001 in HEK293 cells.

pDL001_Hec1-ms_IgG_HC Info/Purchase

Hec1 heavy chain variable and constant region (mouse) + exogenous N-term signal peptide. For co-expression with pDL002 in HEK293 cells.

A diagram illustrating two circular expression plasmids (Heavy Chain Plasmid and Light Chain Plasmid) on the left and a full-length IgG antibody on the right. Each plasmid shows distinct color-coded sections: expression plasmid backbone, signal peptide, heavy chain variable region, light chain variable region, heavy chain constant region, and light chain constant region. The antibody is depicted as a Y-shaped structure with labeled regions that correspond to the plasmid sections.
