CRISPR Abbreviations and Definitions
Whether you’re new to genome editing or an experienced scientist, it can be challenging to keep up with the terminology, definitions, and abbreviations, particularly when it has to do with such rapidly advancing technology as CRISPR.
CRISPR genome editing has revolutionized biological sciences, from medicine to agriculture to industry, making it possible to edit the DNA sequence of almost any living organism. Keeping up with this technology, however, can be overwhelming.
The uses, applications, and techniques of CRISPR seem to expand on a monthly basis, making it necessary to stay on top of the latest CRISPR-related abbreviations. We’re here to make things easier for you! We’ve compiled a handy list of CRISPR abbreviations and definitions to keep on a lab shelf, desk drawer, or back-pocket cheat sheet!
CRISPR and DNA Related Abbreviations
As promised, here are some abbreviations and definitions you will come across during your CRISPR genome editing studies:

DSB – Double-strand break (double-strand DNA break)
dsDNA – Double-stranded DNA
FACS – Fluorescence-activated cell sorting
FASTA – A file format for DNA and protein sequences (it stands for Fast Alignment and Search Tool-All)
gRNA – Guide RNA
GUIDE-seq – Genome-wide unbiased identification of DSBs evaluated by sequencing
HDR – Homology-directed repair
IFN – Interferon
IVT – In vitro transcription

RNAi – RNA interference
RNP – Ribonucleoprotein
S.p. – Streptococcus pyogenes
sgRNA – Single-guide RNA
ssDNA – Single-stranded DNA
ssODN – Single-stranded oligodeoxynucleotide
T7EI – T7 endonuclease I
TALEN – Transcription activator-like effector nuclease
tracrRNA – Transactivating CRISPR RNA
