Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

AsCpf1/Cas12a (Strain BV3L6) Antibody recognizes transfected levels of total AsCpf1/Cas12a (Strain BV3L6) protein. This antibody does not cross-react with Cas9 (S. pyogenes), Cas9 (S. aureus), and FnCpf1/Cas12a (Strain U112) proteins.

Species Reactivity:

All Species Expected

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ile57 of Acidaminococcus sp. Cpf1/Cas12a (Strain BV3L6) protein. Antibodies are purified by protein A and peptide affinity chromatography.

Background

CRISPR-Cas (clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins) are RNA-guided nuclease effectors that are utilized for precise genome editing in mammalian systems (1). Cpf1/Cas12a (CRISPR from Prevotella and Francisella) proteins are members of the Class 2 CRISPR system (2). Class 2 CRISPR systems, such as the well characterized Cas9, rely on single-component effector proteins to mediate DNA interference (3). Cpf1/Cas12a endonucleases, compared to Cas9 systems, have several unique features that increase the utility of CRISPR-based genome editing techniques: 1) Cpf1/Cas12a-mediated cleavage relies on a single and short CRISPR RNA (crRNA) without the requirement of a trans-activating crRNA (tracrRNA), 2) Cpf1/Cas12a utilizes T-Rich protospacer-adjacent motif (PAM) sequences rather than a G-Rich PAM, and 3) Cpf1/Cas12a generates a staggered, rather than a blunt-ended, DNA double-stranded break (2). These features broaden the utility of using CRISPR-Cas systems for specific gene regulation and therapeutic applications. Several Cpf1/Cas12a bacterial orthologs have been characterized for CRISPR-mediated mammalian genome editing (2,4). AsCpf1 (Strain BV3L6)/Cas12a is a Cpf1/Cas12a enzyme derived from Acidaminococcus sp. BV3L6 (5,6).
