MADISON, Wis.–(BUSINESS WIRE)–#CRISPR–Promega Corporation’s new bioluminescent HiBiT
Protein Tagging System
can be combined with CRISPR/CAS9-mediated
gene editing to tag endogenous proteins and simplify their study under
natural expression conditions, as demonstrated in “CRISPR-Mediated
Tagging of Endogenous Proteins with a Luminescent Peptide,”
recently published paper in the journal ACS Chemical Biology.
HiBiT technology, which provides a small, sensitive, easily quantifiable
peptide tag, allows researchers to make better cell models, hastening
efforts in understanding the biology of key human diseases.

“HiBiT really represents a breakthrough in the way we measure protein
trafficking or protein secretion,” says Julian Sebag, PhD, University Of
Iowa Carver College Of Medicine, who is using the HiBiT tag for research
in developing novel treatments for obesity and diabetes. His research
using HiBiT was published last week in BBA
Molecular Cell Research

Kentaro Oh-hashi, PhD, Gifu University, Japan, recently demonstrated
CRISPR-mediated knock-in of HiBiT to study ATF4 protein biology
resulting in the publication of a paper last month in Biochemistry
and Biophysics Reports.

HiBiT enables sensitive detection of tagged proteins down to endogenous
expression levels. The small 11 amino acid HiBiT tag is added to a
protein of interest, which can then be detected and quantified with a
simple luminescent signal. The tag’s small size makes it easy to insert
using CRISPR/Cas9 gene editing, and when combined with the detection
reagent, the resulting bioluminescence is sensitive enough to measure
endogenous protein expression in minutes without the need for antibodies.

Promega launched the new HiBiT
Protein Tagging System
in August and it is already gaining global
attention, receiving a 2017 Product Innovation Award at MipTec,
a leading European exhibition highlighting the latest advances in drug

“We are excited that the simple approach of using HiBiT with CRISPR/Cas9
allows researchers to more easily get at the true biology being studied
to understand the protein dynamics that are a part of normal physiology
or development of disease,” says Marie Schwinn, Promega Senior Research
Scientist and lead author of the Promega paper in ACS Chemical Biology.
