ABSTRACT:
The application relates for method for cloning the gene comprising the steps of: 1. Providing a replication-deficient baculovirus vector, 2. Providing a rescue vector comprising (a) nucleic acid sequence which is capable of restoring replication in the replication-deficient baculovirus vector and (b) at least one gene to be cloned; 3. Causing the replication-deficient baculovirus vector and rescue vector to recombine to produce a replication-enabled baculovirus vector comprising the at least one gene to be cloned; and 4. Growing the replication-enabled baculovirus vector within a suitable invertebrate cell, such as an insect cell. Preferably the baculovirus vector is based upon AcMNPV. Also disclosed are replication-deficient baculovirus vectors, rescue vectors, cells containing such vectors and kits comprising such vectors.
