Vector Construction and Modifications


Fragments such as promoter, enhancer, terminator, secretion leader, IRES, N and C terminal tags, resistance genes, selection markers, and fluorescence protein genes can all be cloned and modified for a shuttle or expression vector.

Lambda based (attB, attP, attL and attR) custom recombination entry and expression vectors can be constructed upon request. This could include vectors capable of doing multiple fragments swaps and exchanges.

Recombinase or ligase linked vector can be custom made for high throughput cloning purpose. We use novel topoisomerase (Shope Fibroma Isomerase) linked vector for directionally cloning of gene of interest.
