Lutropin β CRISPR Activation Plasmid (h) | sc-403297-ACT | 20 µg | $397.00 |
LHB encodes the beta subunit of luteinizing hormone (lutropin beta), a pituitary glycoprotein hormone that heterodimerizes with the common alpha subunit to form bioactive LH. LH signaling through the LHCGR receptor regulates steroidogenesis, ovulation, and luteal function via cAMP/PKA-dependent transcriptional programs and downstream endocrine feedback loops. Altered LHB expression or gonadotropin signaling dynamics are linked to reproductive axis dysfunction, including disorders of pubertal development, infertility, and ovarian or testicular endocrine phenotypes. LHB is therefore a useful target for probing pituitary cell differentiation, hormone biosynthesis and secretion, and gonadotropin-regulated signaling networks.
Lutropin β CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous LHB expression without altering the underlying DNA sequence.
Lutropin β CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the LHB locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the LHB transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Lutropin β expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native LHB locus and enabling the study of Lutropin β-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Lutropin β pathway restoration in tumor cells with silenced or reduced LHB expression.
