Custom cloning-general procedure

Synthesis of the gene of interest (GOI) into an expression vector with the selected features (expression host, affinity tag, signal sequence, etc.). Please download our questionnaire.

Alternative procedure - StarGate Cloning

The use of the StarGate cloning system is of advantage for expression projects, where the best expression features (affinity tags, promoters or expression host) for the gene of interest are unknown.
This service comprise the synthesis of the desired gene into StarGate® Entry Vectors and subsequently the transfer into the StarGate Acceptor Vectors (providing a variety of expression features) with optimal control of expression in E. coli and mammalian cells.

Custom cloning - Requirements for IBA's custom services

The customer is requested to provide the complete gene sequence of interest in electronically readable form or its “Genbank“ accession number. Any information concerning the biochemistry of the protein of interest would be helpful for planning a suitable expression strategy.

This questionnaire will help us to learn more about your project and requirements, please complete it and send it to
A completed S1 Lab biocontainment confirmation form is required as our Lab fulfils biosafety level 1 (S1) standards.
