Protein Laboratories Rehovot Ltd.
PLR produces recombinant proteins for research in E. coli (at present we have ~ 140 proteins in our catalogue) sold mainly abroad. PLR has the know-how to produce expression plasmids and recombinant non-glycosylated tagged and untagged proteins upon request. PLR offers consulting and analytical services to Academic Institutions and Biotech companies in Israel and abroad


Our services include:                                                                  

  • Preparation of recombinant proteins of interest
  • Purification of native and recombinant proteins supplied by the customer
  • Analysis of protein purity by SDS-PAGE, SEC, reverse chromatographWestern Blot analysis and CD spectra
  • Testing biological activity of recombinant proteins in cell-based bioassays
  • Enzymatic assays
  • Pegylation (mainly monopegylation) of recombinant proteins aimed at increase of their half-life in circulation 
  • Growth hormone and prolactin family
  • cytokines
  • Leptin related products
  • Soluble receptors
