An eucaryotic recombinant human growth hormone binding protein (rGHBP) was expressed in baculovirus-infected insect cells and purified by affinity chromatography from culture supernatant. This mannose-rich 34-kDa protein specifically bound human growth hormone (hGH) with the same affinity (kDa = 0.42 x 10(-9) M) than the 51.5 kDa GHBP we purified and characterised from human plasma (kDa = 1.1 x 10(-9) M). A high molecular form of the rGHBP was detected by silver-stained SDS-PAGE, Western blot (mAb 263), affinity cross-linking and Western ligand blot with 125I-hGH. Reduction experiments with beta-mercaptoethanol suggested that this form involved a disulfide bound between two rGHBPs.

D003001 Cloning, Molecular The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells. Molecular Cloning
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.

D006031 Glycosylation The synthetic chemistry reaction or enzymatic reaction of adding carbohydrate or glycosyl groups. GLYCOSYLTRANSFERASES carry out the enzymatic glycosylation reactions. The spontaneous, non-enzymatic attachment of reducing sugars to free amino groups in proteins, lipids, or nucleic acids is called GLYCATION (see MAILLARD REACTION). Protein Glycosylation,Glycosylation, Protein

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. Animal,Metazoa,Animalia
