StarGate® Combinatorial Cloning


These services comprise the precise cloning of the desired gene into IBA’s proprietary StarGate® Entry Vectors and subsequently the transfer into the StarGate® Acceptor Vectors with optimal control of expression in E. coli, yeast, insect or mammalian cells.

General procedure

  • Consulting and planning of the cloning strategy
  • Primer synthesis and PCR with proof-reading DNA polymerase (if necessary)
  • Alternatively, de novo synthesis of the desired gene
  • Entry Cloning into the Entry Vector (basis for all further transfer reactions)
  • Transfer Cloning into customer-defined Acceptor Vector(s)
  • Control sequencing of insert



Entry Cloning (Generation of Donor Vector)


Depending on the gene template provided by the customer, two different Entry Cloning procedures can be performed:

  1. Entry Cloning using gene from gene synthesis

The desired gene is chemically synthesized and cloned into the ENTRY Vector. Codon optimization is performed upon request.

  1. Entry Cloning using PCR from plasmid DNA

The gene of interest (GOI) is amplified by PCR from a plasmid DNA template and is inserted precisely into the ENTRY Vector.

Additional costs for sequencing will be charged per base pair depending on the gene length.

› Time required: 4-8 weeks (depending on the cloning procedure)

Cloning is planned in close cooperation with the client. For example, we can introduce specific point mutations (such as additional restriction sites) into the termini of a gene via PCR cloning.

The original control sequencing print-outs of the gene insert can be provided on request. IBA does not guarantee that the encoded gene will be expressed.



Transfer Cloning into Acceptor Vectors (Generation of Destination Vectors)


After sequence confirmation, the resulting Donor Vector is the origin for highly parallel subcloning of your gene of interest into a multitude of Acceptor Vectors, each providing different functional elements like host specific promoters and a variety of purification tags. Subsequently, the resulting Destination Vectors are transformed into the corresponding host cells for protein expression.
