Vector choice is determined by several factors including size of insert, construction process to be used, desired promoter, and antibiotic resistance. DNA2.0 provides a large selection of cloning vectors, expression vectors and the option to custom clone into your vector.
Recommended Vector Selection Process:
Already know exactly which combination of elements you want? Use the Vector Selector to choose one of our ready-to-use vectors.
Not sure how your protein will behave? Test your gene in several vectors with a variety of properties most likely to increase expression. DNA2.0 offers pre-selected panels for Bacterial Expression, Bacterial Secretion or Mammalian Expression, or you can create your own to explore the properties you think are most important.
Want the very best vector for your system? Working in a non-standard expression system, a particularly difficult protein, or need even higher yields of active protein? DNA2.0 will create unique combinations and configurations of vector components using our machine learning technology, to create a custom vector exactly suited to your needs.
DNA2.0 synthetic genes can be cloned into our own series of vectors, designed to minimize common restriction sites for ease of downstream manipulation. Inserts are flanked by transcriptional terminators to allow cloning of inserts encoding proteins that are toxic to E. coli.
- The cloning vectors do not contain restriction sites for excision of your gene. These must be included in your gene design if you wish to remove your gene with restriction enzymes.
- Gentamicin resistance is present in some vectors, but functionality may be limited.
- For PCR or sequencing primers we use the following oligonucleotides:
- pTF 5′-CTCGAAAATAATAAAGGGAAAATCAG-3′
- pTR 5′-TGGTAGTGTGGGGACTC-3′
- Inserts are cloned nondirectionally to minimize potential toxicity of inserts.

Convenient – clone your genes with Electra Vectors and Cloning kit, or have DNA2.0 do the work for you
Efficient transfer of your ORF into multiple expression vectors with varying features using the DNA2.0 Electra system. An ORF of interest (Gene A) can be easily transferred from the mother vector (pMOTHER) into a range of DAUGHTER vectors (pDAUGHTERs). DAUGHTER vectors are available in Bacterial, Mammalian and Yeast vectors with your choice of resistance markers, fluorescent protein stuffers and C- and N-terminal tags and/or fusions.
Your Gene in Your Vector
DNA2.0 can custom clone your synthesized gene into your chosen vector.
Simply provide DNA2.0 with the custom vector and we will handle the cloning and sequencing. DNA2.0 fully protects your IP and confidentiality at all times; and of course, the custom vector shall remain your property throughout the cloning process.
Your Vector in Your Account: Once you have used a custom vector for your gene synthesis order, your vector will be available to your account for any future orders. Easily select your favorite vector with the click of a button.
Please note: additional fees apply for Custom Cloning.
