Catalog Number:

Our lab generates a lot of protein knockouts in mouse embryonic stem cells using crispr-cas9 technology. We use Western Blots and subsequent sequencing to screen potential knockout clones.

Experimental Design and Results Summary

Applications

Western Blot

Sample

Whole cell lysates from mouse ES cells

Primary Incubation

1:500 dilution overnight in 5% milk buffer at 4C

Blocking Agent

5% milk in PBST

Secondary Incubation

1:3000 anti-rabbit secondary at RT for 1 hour

Tertiary Incubation

NA

Detection

Exposure with SuperSignal™ West Femto Maximum Sensitivity Substrate, imaged with apparatus from Bio-Rad

Results Summary

Antibody only picks up strong nonspecific bands, making it useless. It's possible that the weak band is specific, though it is hard to tell, especially because of the stronger nonspecific band above it. We confirmed candidate 13 as a true knockout using sequencing subsequently.

Additional Notes

Summary

The Good

Relatively cheap antibody

The Bad

Strong non-specific band

The Bottom Line

Wouldn't recommend.
