Hi.. Everyone I have been attempted to Clone the Oligo sequence into the LentiCRISPRv2 backbone plasmid but I'm unable to get the colonies when I transformed in DH5alpha. I have followed the Addgene protocol (http://genome-engineering. org/gecko/wp-content/uploads/ 2013/12/lentiCRISPRv2-and- lentiGuide-oligo-cloning- protocol.pdf).
Even I tried different time interval and ratio of vector: insert.
Thank you
