KMD Bioscience has a mature antibody production platform with well-established antibody engineering technology to ensure the quality of service. KMD Bioscience has extensive experience in antibody library construction and supported by our technology and platform, KMD Bioscience can provide high-quality human Fab antibody library services. KMD Bioscience is constantly upgrading its technology to better serve your needs. With many years of research and development, KMD Bioscience has established a solid platform for Fab library construction. Our scientists can offer high-quality phage display library construction and custom phage display library screening services to precisely meet our clients' demands.
Human Fab Antibody Libraries:
The Fab antibody library refers to VH and VL, especially the CDR region genes of the antibody form a large number of different clones by different strategies, such as amino acid mutations and frameshift mutations. In addition, KMD Bioscience can provide a suitable solution: after sensitizing human peripheral blood monocytes in vitro, high-affinity monocytes were isolated by flow cytometry, and then EBV monoclonalization was conducted. Using this method, highly consistent monocyte clones can be obtained, then carry out library construction.
