I would like to use your ORFEXPRESS™ Shuttle clone to express a protein with an N-terminal or C-terminal fusion protein, is that possible?

Answer: Yes, and there are two choices. First, you can use the OmicsLink™ Expression Clones that we have developed. We have already constructed ORF clones in expression vectors with N-terminal tags or C-terminal tags, such as His tag and eGFP, there are more than 10 types of targs to meet your need. Please check OmicsLink™ product information page (https://www.genecopoeia.com/tech/omicslik/). Second, you may also use Invitrogen's Gateway® expression vectors for expressing N-terminal or C-terminal fusion proteins. Because our ORFEXPRESS™ Gateway® Shuttle Clones contains stop codons, you will need to remove the stop codons before transferring ORF inserts into Invitrogen's pDEST expression vectors to produce C-terminal tagged fusion proteins.

You claimed that your ORFEXPRESS™ Gateway® Shuttle Clones are Gateway® cloning technology compatible, what does it mean?

Answer: The vector for ORFEXPRESS™ Gateway® Shuttle Clones manufactured by GeneCopoeia, Inc. (GCI) harbors full length ORFs flanked by attL1 and attL2 recombination sites that pair with the Gateway® pDEST expression vectors containing attR1 and attR2 recombination sites. When GCI's ORFEXPRESS™ Shuttle Clones are mixed with Gateway® compatible pDEST expression vector(s), with optimal concentrations of enzymes and conditions, the ORFs in the ORFEXPRESS™ Shuttle clones can be transferred into Gateway® pDEST expression vector(s). Because of the unique feature of recombination sites in the vectors, the transferred ORFs will be under the control of the promoter(s) in the destination expression vector(s).

 

Why should I choose full-length ORF clones over other full-length cDNA clones?

Answer: The full-length ORF clones contain only the protein coding sequences, while other full-length whole transcript cDNA clones contain non-coding sequences, such as 5' and/or 3' UTRs, which have been known to have possible negative impact on the protein translation process.
