FAQs

• What are the advantages of using base editing for gene modification compared to CRISPR-Cas9?

  Unlike CRISPR-Cas9, which creates double-strand breaks (DSBs) in DNA, base editing enables precise single-nucleotide conversions (C-to-T or A-to-G) without inducing DSBs or requiring a donor DNA template. This approach reduces the risk of unwanted insertions or deletions (indels), minimizes off-target effects, and lowers cellular stress, making it a safer and more efficient gene editing method, especially in non-dividing cells.

• What purity levels do you offer for base editing gRNA synthesis?

  We offer both desalt-purified and HPLC-purified base editing gRNA, in both non-clinical (RUO and IND-enabling) and clinical (cGMP) grades.

• What is the maximum quantity of base editing gRNA that can be ordered?

  We can deliver up to 100 nmol base editing gRNA as part of our standard offering. For other quantities, please inquire here.

• Besides base editing gRNA, what additional reagents will I need to perform base editing?

  In addition to base editing gRNA, base editing requires a base editor enzyme, delivered in either mRNA or protein form. The base editor, which consists of either a deactivated Cas protein (dCas9) or Cas9 nickase (nCas9) with either a cytidine or adenine deaminase- is guided by the gRNA to an editing window of about 4-9 nucleotides where it performs a precise C-to-T or A-to-G DNA base conversion.

  GenScript offers CBEmax mRNA (Cat# RP-A00002) and ABE8e protein (Cat# RC00010), both available off-the-shelf.

• What container and delivery formats are available for base editing gRNA?

  Our base editing gRNA can be delivered in either single tubes or 96-well plates, formatted as dry powder or suspended in TE buffer (pH 8.0, 100 µM) or nuclease-free water (100 µM).

• How should I store base editing gRNA?

  Dissolve the powdered base editing gRNA in TE buffer to a concentration of 100 pmol/µL, or other desired concentration. Divide into aliquots of at least 10 μl each and store at -20℃ for up to 6 months, avoiding repeated freeze-thaw cycles. For long-term storage, store at -80℃.
