LMX1B Lentiviral Activation Particles (h) | sc-402945-LAC | 200 µl | $455.00 |
LMX1B encodes a LIM homeobox transcription factor that directs cell fate specification and differentiation programs during development, with particularly strong roles in dorsal limb patterning, glomerular podocyte maturation, and midbrain dopaminergic neuron identity. By binding regulatory DNA elements and coordinating cofactor-dependent transcriptional networks, LMX1B influences pathways governing cytoskeletal organization, extracellular matrix dynamics, and lineage-restricted gene expression. Altered LMX1B activity is linked to congenital limb and kidney phenotypes and is frequently studied in contexts of podocyte dysfunction, developmental gene regulation, and neuronal specification. As a nuclear transcriptional regulator, LMX1B serves as a tractable node for dissecting gene regulatory circuitry and enhancer-driven control of tissue-specific programs.
LMX1B Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient LMX1B upregulation across a broader range of human cell types.
LMX1B Lentiviral Activation Particles (h) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the LMX1B transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous LMX1B expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native LMX1B genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
