Designing and using RNA scaffolds to assemble proteins in vivo

RNA scaffolds are synthetic noncoding RNA molecules with engineered 3D folding harnessed to spatially organize proteins in vivo. Here we provide a protocol to design, express and characterize RNA scaffolds and their cognate proteins within 1 month. The RNA scaffold designs described here are based on either monomeric or multimeric units harboring RNA aptamers as … Read moreDesigning and using RNA scaffolds to assemble proteins in vivo

A Programmable Dual-RNA–Guided DNA Endonuclease in Adaptive Bacterial Immunity

Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems provide bacteria and archaea with adaptive immunity against viruses and plasmids by using CRISPR RNAs (crRNAs) to guide the silencing of invading nucleic acids. We show here that in a subset of these systems, the mature crRNA that is base-paired to trans-activating crRNA (tracrRNA) forms a … Read moreA Programmable Dual-RNA–Guided DNA Endonuclease in Adaptive Bacterial Immunity

Apps Collections for Synthetic Biology


Synthetic biology which is inspired by “plug-and-play” concept is supported by standardized biobricks and also computational tools for analysis and optimization [1]. Here are bio-apps collections for you. Personally Tinkercell and UNAFold are mostly used.

Circuit design and simulation
Circuit optimization
DNA and RNA design
 Gene Designer
