hsa-miR-548ba

제품 개요

Sigma의 MISSION® Lenti-miRs는 공통 백본에서 microRNA를 발현하도록 설계된 렌티바이러스 기반 시스템입니다. 이 구조는 정확한 Dicer 처리를 보장하며, 상보적 가닥은 독자적인 알고리즘을 통해 백본 구조의 염기쌍 패턴을 모방하도록 설계되었습니다. 각 miRNA 구성체는 TRC2-pLKO-puro 벡터에 클로닝되어 서열 검증을 거쳤으며, 성숙 microRNA 서열은 miRBase에서 확보되었습니다.

제품 설명

Lentiviral transduction particles are produced from sequence-verified lentiviral plasmid vectors. Oligos containing the microRNA sequences are cloned into the TRC2-pLKO-puro vector. Co-transfection of this vector into the appropriate cell line with compatible packaging plasmids produces viral particles that can be used to transduce mammalian cells.

The polymerase II promoter, elongation factor 1 alpha (EF1A), was chosen to drive miRNA expression needed for reverse transcription of viral RNA and integration of viral DNA into the host cell genome. Additionally, the Woodchuck Hepatitis Post-Transcriptional Regulatory Element (WPRE) allows for enhanced expression of transgenes delivered by lentiviral vectors.

This lentiviral vector also carries a puromycin resistance gene for selection of cells. Unlike murine-based MMLV or MSCV retroviral systems, lentiviral-based particles permit efficient infection and integration of the specific miRNA construct into both differentiated and non-dividing cells, such as neurons and dendritic cells.
