The TGEX™ Vector Series is designed for the rapid transient expression of antibodies under varied formats (full antibodies, Fab fragments, Fc fusions, scFv-Fc fusions). Yields in widely available mammalian cell culture systems in suspension and serum-free conditions are between 10 mg/L and 100 m g/L in just a few days.

M13KO7d3 is a novel helper phage engineered for multivalent phage display. M13KO7d3 lacks a functional gene III driving the display of pIII-fusion proteins expressed by the phagemid. M13KO7d3 is similar to pIII-defective helpers such as Hyperphage, Ex-Phage or Phaberge that have been shown to increase display of scFv by a factor up to 100-fold and more.

hage-Competentâ„¢ cells are concentrated stabilized bacterial cells with multiple applications in phage display. These cells can undergo multiple freeze-thaw cycles without losing their titer and can be expanded without latency to generate large volumes of cells ready for transduction. Phage infectivity is usually equal or higher than infectivity measured on bacteria freshly prepared and transduction gives more reliable and reproducible numbers of cfu and pfu. Today we are pleased to make TG1 and SS320 cells available under this new format.

hagemid vectors pADL-20c, pADL-22c, and pADL-23c are now available in store. To get full advantage of the amber suppression for expression of soluble antibodies and direct detection without sub-cloning, we adjusted the level of expression to match the high expression vector pCOMB3, a popular phagemid known for its robust display and moderate toxicity. A transcription terminator has been added after gene III to prevent excessive production of beta-lactamase during induction period.

CM13 Interference-Resistant Helper Phage is a new, well-characterized mutant of M13KO7 producing on average twice as many virions than M13KO7 with the same level of display. CM13 is well-tolerated by the bacterial host and is compatible all filamentous phage display systems. Our new formulation gives you enough helper to surperinfect up to 1,000 ml of bacterial culture.

ew versions of the pADL phagemid vectors pADL-20b, pADL-22b, and pADL-23b are now available. The sequence of the Amp(R) gene sequence has been modified, allowing the cloning site to be opened by either SfiI or BglI restriction enzyme. This modification results in lower background during cloning and brings more flexibility for designing libraries. The pADL vector series is a collection of phagemid vectors for controlled display on the minor coat protein III which combines HIS tag for purification, epitope tag for detection and amber stop codon for conditional display. Expression of the fusion protein is tightly controlled, eliminating issues with toxic clones and library misrepresentation.
