Characteristics：SpCas9 is derived from Streptococcus pyogenes, a type of bacteria that uses the CRISPR-Cas9 system as part of its immune defense mechanism against viral infections. SpCas9 is widely used in genome editing due to its ability to target and cut specific DNA sequences with high precision.
The TBG promoter is derived from the human thyroxine-binding globulin gene, which plays a role in thyroid hormone transport. Its specificity and relatively strong activity in the liver make it a valuable tool for studies and therapeutic applications aimed at treating liver-related conditions.
