EosFP - Green to Red Photoconvertible Fluorescent Protein for Local Marking

Our portfolio of fluorescent proteins has been extended by a new fluorescent protein that allows UV/blue-inducible, permanent, bright and fast photoconversion from green to red wave length. These properties make it an excellent choice as a marker for tracking of cells, compartments or proteins in live cells, as well as a nanoscopy marker using photoactivated localization microscopy (PALM).

New brochure on Molecular Screening Technology

This 16-page brochure focuses on several yeast one- and two-hybrid systems and a phagemid system, that are useful for high-throughput molecular screening of protein-protein and DNA-protein interactions. Further tools, such as biochemical assays, immunological and fluorescence-based methods, are available from MoBiTec as well. The yeast two-hybrid system has rapidly become one of the most widely used techniques in molecular biology. It still is the method of choice to identify protein-protein interactions from either cDNA libraries or known gene sequences in vivo. The method relies on the transactivation of reporter genes in Saccharomyces cerevisiae identifying positive interactions.

Grow’n’Glow GFP Reporter Systems

MoBiTec’s Grow’n’Glow one- and two- hybrid systems are powerful tools for gene discovery and functional analysis. A GFP reporter allows one-step selection of positive clones under UV light.

Y2H Membrane Systems

MoBiTec’s split-ubiquitin based systems circumvent the restrictions that are usually associated with traditional Y2H systems, now allowing to detect interactors with integral membrane proteins, self-activating and transcriptionally active proteins.

  • Y2H Membrane System
    Versatile, reliable detection and analysis of specific binding partners of full-length integral membrane and membrane-associated proteins.
  • Y2H Transactivating Protein System
    Screens transcriptionally active and self-activating proteins that cannot be screened using classical Y2H systems.

Tools and Media

MoBiTec offers many tools optimized for working with Y2H and yeast: Kits to transform yeast cells, kits to purify plasmids from yeast, media, supplements and fermentation technology.

Phagemid System

  • Phagemid Display System
    Easy-to-handle, fast and low-cost approach for highthroughput and high-content screening of protein-protein interactions.
