SIRT2 Knockout Cell Line (MH-S)

The choice depends on whether you are studying SIRT2's role as a cytoplasmic NAD⁺-dependent deacetylase or its functions in macrophage immunology and inflammatory response. The Knockout line is the standard tool for asking whether SIRT2 is required for tubulin deacetylation, NLRP3 inflammasome regulation, and microglial/macrophage immune signaling — particularly relevant in MH-S, a mouse alveolar macrophage cell line. Overexpression is useful for studying SIRT2's effects on inflammation or cancer biology. For macrophage immunology research, the EDITGENE Sirt2 Knockout in MH-S is highly informative — MH-S is the standard murine alveolar macrophage model, and SIRT2 has emerging roles in macrophage polarization, inflammatory cytokine production, and NLRP3 inflammasome activity. Rescue with wild-type or catalytically-dead (H187Y) SIRT2 is the standard specificity control. SIRT2-selective inhibitors (AGK2, AK-7) specificity testing benefits from this knockout.

Primary applications: • Microtubule biology: acetylated α-tubulin (K40) Western blot and immunofluorescence to assess SIRT2-dependent tubulin deacetylation. • Macrophage inflammatory response: LPS-induced cytokine production (TNF-α, IL-6, IL-1β) and NLRP3 inflammasome activation in Sirt2-deficient alveolar macrophages. • Macrophage polarization: M1/M2 marker expression following polarizing stimuli to characterize SIRT2's role in macrophage phenotype. • SIRT2 inhibitor specificity: critical genetic control for AGK2, AK-7, and other SIRT2-selective compounds in inflammation drug development. EDITGENE recommends this model for researchers investigating macrophage biology, pulmonary inflammation, SIRT2-mediated immune regulation, and SIRT2-targeted pharmacology.

Yes. SIRT2 rescue experiments require attention to cytoplasmic targeting: • Construct design: use a codon-modified Sirt2 sequence with a small C- or N-terminal tag (FLAG, HA). SIRT2 has multiple isoforms with distinct N-termini — choose the isoform appropriate to the experimental question. • Catalytically-dead rescue: the H187Y mutation abolishes deacetylase activity and is the standard specificity control. • Tubulin deacetylation rescue: restoration of acetyl-tubulin levels by Western blot confirms catalytic rescue. • Inflammatory rescue: NLRP3 inflammasome and inflammatory cytokine production should be restored to confirm immune-relevant rescue. MH-S is a murine alveolar macrophage cell line — transduction with lentivirus is supported but may require optimization compared to non-macrophage lines.
