Why there is no indel in targeted exons after using CRISPR-Cas9 plasmid PX459? Western blot says there is no protein at the appropriate MW.

I have 5 cell lines now, which has no bands on western blot if I checking my protein. To make sure about the knock-out, I PCR amplified the targeted exons and sent to sequencing (checked the bands...
