Development of a novel mammalian cell surface antibody display platform

Mammalian Cell Surface Display as a Novel Method for Developing Engineered Lectins with Novel Characteristics

Leguminous lectins have a conserved carbohydrate recognition site comprising four loops (A-D). Here, we randomly mutated the sequence and length of loops C and D of peanut agglutinin (PNA) and expressed the proteins on the surface of mouse green fluorescent protein (GFP)-reporter cells. Flow cytometry, limiting dilution, and cDNA cloning were used to screen for several mutated PNAs with distinc...

Development of a Novel Inhibitory Chimeric Anti-HER2 Monoclonal Antibody

Lymphocyte Display: A Novel Antibody Selection Platform Based on T Cell Activation

Since their onset, display technologies have proven useful for the selection of antibodies against a variety of targets; however, most of the antibodies selected with the currently available platforms need to be further modified for their use in humans, and are restricted to accessible antigens. Furthermore, these platforms are not well suited for in vivo selections. We present here a novel cel...

Mammalian cell surface display for monoclonal antibody-based FACS selection of viral envelope proteins

The elicitation of broadly and efficiently neutralizing antibodies in humans by active immunization is still a major obstacle in the development of vaccines against pathogens such as the human immunodeficiency virus (HIV), influenza virus, hepatitis C virus or cytomegalovirus. Here, we describe a mammalian cell surface display and monoclonal antibody (mAb)-mediated panning technology that allow...

Microbial Cell Surface Display: Its Medical and Environmental Applications

Cell-surface display is the expression of peptides and proteins on the surface of living cells by fusing them tofunctional components of cells which are exposed to the environment of cells. This strategy can be carriedout using different surface proteins of cells as anchoring motifs and different proteins from different sourcesas a passenger protein. It is a promising strategy...
