New: FAST-Licase Cloning

Published January 29, 2017
A

ntibody Design Labs is proud to announce the availability of the FAST-Licase™ cloning system. FAST-licase enables the ultra-fast cloning in just a few seconds of two or more DNA fragments by homologous recombination. This novel toolbox for the molecular biologist rethink traditional cloning with immense savings of both time and money.

New Phagemid Vector pADL-100™ Series for Peptide Display

Published July 01, 2016
P

hagemid vector pADL-100 is now available in store. The pADL-100™ phagemid series offers the highest levels of display and multivalency necessary for the successful selection of peptides of low to very low affinity. This new vector is your best choice for the display of peptide libraries.

W

e now offer sequencing of antibodies and cloning into any formats as a service into any of our expression vectors. Once we have the clone, we can express your antibody at any scale. Seamless ordering, fast & reliable delivery. Please inquire HERE.

Validating Phage Clones as scFv-Fc Fusions

Published October 01, 2015

The TGEX-SCblue vector let you transfer scFv fragments seamlessly between phage clones and an Fc fusion cassette thanks to a common double SfiI site, enabling easy and rapid validation of new antibodies as scFv-Fc fusions.

TGEX Mammalian Expression Vector Series

Published October 01, 2015

TheTGEX™ 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.

Novel pIII-Defective Helper Phage Enhances Display

Published May 08, 2015


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.

Phage Competent Cells to Streamline Phage Display

Published April 07, 2015
P

hage-Competent™ 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.

New Phagemid Vectors from the pADL™-20 Series Mimics pCOMB3

Published November 24, 2013

P

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.

Custom Immunized Phage Display Antibody Libraries

Published April 29, 2013
W

e now offer the design and building of antibody libraries from immunized animals as a service. You provide the antigen; we conduct the immunization, design and build the antibody library for you as a service. Phage display is a straightforward approach to isolate high affinity monoclonal antibodies from small, focused libraries build from immunized animals. These libraries are of moderate size, between 1 and 10 million clones and usually mirror the animal immune response; high affinity antibodies, similar to antibody generated by hybridoma technology, are isolated from them by straightforward selection techniques. We have extensive experience in building phage antibody libraries in varied formats and display types.
