Hi everyone, I am new on CRISPR strategies and I am looking for a single gene transcriptional activation method. I was wondering if I can use the lentiSAM v2. plasmid (75112) for a single target gene activation and how to use it in a two-vector strategy.
Also I was questioning whether the sgRNAs design (flanking sequences) is the same for lentiSAMv2 backbone and lentisgRNA(MS2)_zeo (61427).

Is Synergistic Activation mediator intended solely for activation libraries or also for single gene targeting? 
I am thinking also about LentiCRISPRv2 and LentiGUIDE-Puro?

Basically, I have a plasmid dCAS9-VP64-MSloops (Addgene #75112) and I would like to know how to digest it to ligate my designed oligos. I was thinking to use BsmBI, but I am not sure about the digestion I will obtain

Hi,

You can use golden gate assembly to very efficiently clone your sgRNA. Please refer to the validation section of our screening protocol for details on reaction setup.

Hi, 

I'm also planning to do CRISPRa targeting single gene (not genome wide screen).

1. It seems all the plasmid I need is lentiSAM v2 (75112) and lenti MPH v2 (89308), correct? (2-vector system)
2. LentiSAM v2 (75112) seems to be able to clone sgRNA, but I couldn't find specific protocol for this.
Is the following SAM cloning protocol also valid for LentiSAM v2?

If so do the golden gate reaction still necessary for cloning single sgRNA?
Or is it still possible using ordinary cloning protocol like in lentiCRISPR v2?

Thanks in advance.

Best,
Hiroyuki

Hi Hiroyuki,

To answer your questions:
1. Yes those plasmids are sufficient.
2. Yes you can use the SAM cloning protocol, which uses Golden Gate assembly. Doing Golden Gate assembly will be much more efficient than the ordinary protocol, but both strategies work.

Best,
Julia

One question, Will genetic engineering used for aesthetic reason? Such as having blue eyes, be taller, etc? Will that be allowed? If the answer is no, why? People Will want it for aesthetic reason for their children.
