Anti-LbCas12a (Cpf1) antibody, Mouse monoclonal

半岛bd体育手机客户端 说明

一般描述

Clustered, regularly interspaced, short palindromic repeat (CRISPR) systems encode RNA-guided endonucleases that are essential for bacterial adaptive immunity. Depending on the architecture of the effector-CRISPR RNA (crRNA) interference module, different CRISPR-Cas systems could be assigned into two classes1: class 1 systems of multi-subunit complex, such as Cascade and class 2 systems of single enzyme, such as Cas9.
Cpf1 (CRISPR from Prevotella and Francisella 1) belongs to class 2 type V CRISPR-Cas endonuclease system. Cpf1 comprise several differences from Cas9 protein including cleavage with 5′ overhangs, a shorter guide RNA and a longer distance between the seed sequence and cleavage site.
LbCpf1, Cpf1 from Lachnospiraceae bacterium ND2006, was examined together with 15 members of Cpf1 nuclease family and proved to mediate efficient genome editing in HEK293FT cells with improved results compared to SpCas9.5 According to thr crystal structure, LbCpf1 has a triangle-shaped architecture with a large positively charged channel at the centre.7 The crRNA binding was shown to induce the pronounced structural rearrangements of LbCpf1, leading to formation of a substrate-binding conformation of LbCpf1. Over-expressed in plant cells, LbCpf1 demonstrated more than 10-fold transcriptional repression of the target gene.
Monoclonal anti-LbCpf1 antibody can provide a useful tool for genome editing research, such as detecting and monitoring LbCpf1 positively transfected cells.

免疫原

Recombinant LbCpf1

应用

Monoclonal Anti-LbCpf1 specifically recognizes Cpf1 from Lachnospiraceae bacterium ND2006. The product may be used in several immunochemical techniques including Immunoblotting (～135 kDa), Immunofluorescence and Immunoprecipitation. Monoclonal Anti-LbCpf1 does not cross react with Cpf1 from Acidaminococcus sp. (strain BV3L6) ), SpCas9 from Streptococcus pyogenes bacteria and FnCas9 from Francisella novicida bacteria.

外形

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

储存及稳定性

For continuous use, store at 2-8 ℃ for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.

其他说明

This product is for R&D use only, not for drug, household, or other uses.
In order to obtain best results in different techniques and preparations we recommend determining optimal working concentration by titration test.
