Delivery of Nucleic Acids with RJH Biosciences Reagents

RJH Biosciences facilitates delivery of nucleic acids to biological systems, including siRNA, mRNA, pDNA, miR and ASO. Our polymeric reagents provide stable and effective delivery of polynucleotides in various cell types and animal models. RJH reagents allow your studies in cell culture and animal models to be executed in a way that is safe and reliable. We are dedicated to:

  • Providing 8 different commercial reagents that work in a variety of cells and cover multiple nucleic acids. More information can be found here.
  • Engaging in mutually beneficial collaborative partnerships.
  • Undertaking contract R&D activities for clients that identify delivery vehicles for specific nucleic acids, cell types and lead optimization.

Implementing CRISPR-Cas9 Technology using RJH Reagents 

CRISPR technologies have been increasingly utilized in research and therapeutic development. RJH has been collaborating with leading CRISPR experts to validate our reagents for CRISPR applications. The following shows Prime-Fect and other RJH reagents used for gene editing using pDNA-based CRISPR-Cas9 technology.

Figure. Top: Endonuclease assays of WTAP and RunX editing using CRISPR-Cas9. Transfection of the cells was performed with Prime-Fect and Lipo3000. Multiple DNA bands indicate positive DNA cleavage by the Cas9 endonuclease. Bottom: Relative transfection efficiencies of CRISPR-Cas9 plasmid by a leading lipofection product as compared to four RJH reagent formulations.

Our reagents provide high transfection efficiencies as compared to leading market reagents that lead to strong gene editing. A full testimonial on RJH reagents in CRISPR applications can be found here. Contact us if you are interested in using our reagents for plasmid and protein based (RNP) CRISPR technology.
