This fully updated volume explores notable developments in the field of mammalian cell-based recombinant protein production. Beginning with methods for transient recombinant protein production, the book continues with methods for stable cell pool generation, protein production using stable clonal cell lines, as well as high-throughput screening technologies for characterizing transient cell surface protein ectodomain expression and for identifying host genes involved in protein production. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
