The baculovirus-insect cell system is effective in the production of large quantities of biologically active recombinant proteins. The secretory production of an antibody Fab fragment in lepidopteran insect cells infected with a recombinant baculovirus that contains both the heavy-chain (Hc; Fd fragment) and light-chain (Lc) genes of the Fab fragment is described in this chapter. The recombinant baculovirus can be generated rapidly and efficiently through site-specific transposon-mediated insertion of foreign genes into a baculovirus genome called a bacmid in Escherichia coli. Factors influencing the Fab fragment production are discussed.

UI	MeSH Term	Description	Entries
D007140	Immunoglobulin Fab Fragments	Univalent antigen-binding fragments composed of one entire IMMUNOGLOBULIN LIGHT CHAIN and the amino terminal end of one of the IMMUNOGLOBULIN HEAVY CHAINS from the hinge region, linked to each other by disulfide bonds. Fab contains the IMMUNOGLOBULIN VARIABLE REGIONS, which are part of the antigen-binding site, and the first IMMUNOGLOBULIN CONSTANT REGIONS. This fragment can be obtained by digestion of immunoglobulins with the proteolytic enzyme PAPAIN.

D005822	Genetic Vectors	DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D016367	Baculoviridae	Family of INSECT VIRUSES which contain polyhedron-shaped or ovocylindrical occlusion bodies. The genera include ALPHABACULOVIRUS; GAMMABACULOVIRUS; and DELTABACULOVIRUS (commonly known as NUCLEOPOLYHEDROVIRUSES) and BETABACULOVIRUS (commonly known as GRANULOVIRUSES). Baculovirus vectors are used for expression of foreign genes in insects and as BIOPESTICIDES for controlling insect populations.	Baculovirus,Baculoviruses
