Background
MCL1 (myeloid cell leukemia 1) is an anti-apoptotic member of the BCL-2 protein family that promotes cell survival by sequestering pro-apoptotic BH3-only proteins and the effectors BAX and BAK, thereby preventing mitochondrial outer membrane permeabilization. Unlike other BCL-2 family members, MCL1 has a short half-life and is rapidly regulated by transcription, ubiquitin-mediated degradation, and signaling inputs, allowing dynamic control of cell fate. MCL1 is essential for the survival of many cell types, including hematopoietic and lymphoid cells. It is frequently amplified or overexpressed in cancers, where it supports tumor cell survival and resistance to therapy, making it an important oncology target.
Product Description & Applications
The Human MCL1 shRNA Lentivirus delivers validated short hairpin RNA targeting MCL1 from a third-generation, self-inactivating lentiviral backbone. shRNA expression is driven by a U6 promoter, with a co-expressed fluorescent reporter (GFP or RFP) and antibiotic selection marker. VSV-G pseudotyping enables broad tropism across primary, suspension, and cryopreserved cells, and each shRNA is validated for at least 70% MCL1 knockdown by a fluorescence-based method.
High-titer particles are ultra-purified by PEG precipitation and sucrose gradient centrifugation. A shRNA set option provides a mix of two independent validated shRNAs plus a scrambled control. Applications include loss-of-function studies of apoptosis, cell survival, and resistance to anticancer therapy.
About This Product
This validated shRNA lentivirus targeting MCL1 (NCBI Accession: NM_021960.5) delivers a 19–20 bp shRNA from a third-generation, self-inactivating lentiviral backbone. Expression is driven from a U6 Pol III promoter, with a constitutively expressed fluorescent reporter (GFP, GFP/Luc, RFP, RFP/Luc) and antibiotic selection marker (Blasticidin, Puromycin) co-expressed from the same vector. VSV-G pseudotyping enables broad cell tropism, including primary, suspension, and cryopreserved cell types.
Knockdown is validated using a proprietary bicistronic fluorescence assay in which the target mRNA is co-expressed fused to RFP alongside the shRNA-GFP construct. At least 70% reduction in RFP signal in GFP-positive cells confirms on-target activity — a more direct functional readout than transcript-level qPCR. Polyclonal stable lines can be generated by antibiotic selection within 10 days, preserving parental cell heterogeneity compared to single-clone CRISPR approaches.

Common customization requests
- Insert / payload: replace the gene/sequence, swap to a different isoform, add mutations, or optimize cloning features.
- Expression design: change promoter (e.g., CMV/EF1α/PGK), add enhancers, or adjust regulatory elements.
- Reporters: add/swap GFP/RFP/mCherry/luciferase (single or dual reporters where applicable).
- Selection markers: add/swap puromycin/blasticidin/neomycin or fluorescent selection options.
- Vector format: switch between OE, shRNA, CRISPR (sgRNA/Cas systems), or control vectors (where supported).
Add-ons you can request
- Control viruses: empty vector, non-targeting shRNA, reporter-only controls, or matched backbone controls.
- Packaging / format: concentration options, aliquoting, or custom fill volume for screening workflows.
- Documentation: construct map/sequence confirmation package (as available) and batch documentation.
What to include in your request
- Target cell type/model (cell line or primary cells) and intended readout (reporter, knockdown, OE, etc.)
- Insert sequence (FASTA) or reference ID, plus any required tags/mutations
- Promoter, reporter, and selection marker preferences
- Desired scale and preferred format (aliquots / concentration requests)
