Human IL3 encodes interleukin-3 (IL-3), a hematopoietic cytokine that regulates survival, proliferation, and differentiation of myeloid and early progenitor populations. IL-3 signals through the IL-3 receptor complex (IL3RA/CD123 with the common β chain CSF2RB), engaging JAK/STAT, PI3K–AKT, and MAPK/ERK cascades to modulate lineage commitment and inflammatory output. Dysregulated IL-3–CD123 axis activity has been implicated in aberrant myelopoiesis and immune-cell activation states, supporting investigation in leukemia biology, bone marrow microenvironment studies, and cytokine-driven inflammation models. As a secreted factor, IL-3 is also useful for dissecting paracrine signaling and receptor trafficking in hematopoietic and immune cell systems.
IL-3 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the IL3 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within IL3. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt IL3 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of IL3-disrupted clones.
