It's a composite part encoding our gRNA promoted by Human U6 promoter.
The composite part encodes our specific gRNA promoted by Human U6 promoter. It is utilized to guide the Cas9 protein to the BRAF V600E mutation.

Usage and Biology
Single-guide RNA (SgRNA) is an artificial RNA which is designed to bind a certain DNA sequence. It can combine with Cas9 protein to play a role in the cleavage of target DNA.It is much shorter but have the same function as the original RNAs in CRISPR-Cas-9 system.
We design the gRNA for BRAF V600E to specifically target this mutant gene in melanoma cells while it has no effect on normal cells.

Functional Parameters
In order to demonstrate our CRISPR/Cas9 system in melanoma cell lines, we extracted genome of two different human melanoma cell lines (A375 and G361) with BRAF V600E mutation after transfection. A375 is a melanoma cell line with BRAF V600E homozygous mutation while G361 is with heterozygous mutation and comparison can made between the outcome of them.
The cell genome was treated with TA cloning Assay. Twenty-one single clones from the transfected cells were selected for DNA sequencing and result showed that BRAF gene was cleaved in three of them and the wild-type BRAF wasn’t cleaved in two of them. Results showed that the CRISPR/Cas9 system specifically cleaved the mutant, but not wide-type BRAF gene in melanoma cells.
