AviTag/BirA Biotinylation Preserves IL7 Activity
2026-09-25
This study compared AviTag/BirA-mediated site-specific biotinylation of IL7 with chemical random biotinylation. The site-specifically modified protein retained T-cell activity better in the reported assays; streptavidin-complexed IL7 also persisted longer in mouse blood than free IL7. The work addresses protein biotinylation, not tyramide signal amplification or proximity labeling.

Early Life Adversity, Oxytocin, and Visual Defense
2026-09-05
Tan et al. show that social deprivation during a defined postnatal period weakens looming-evoked innate defensive behavior in mice and links this deficit to reduced oxytocin signaling in the superior colliculus. The study combines behavioral testing, molecular analysis, circuit manipulation, and intranasal oxytocin to connect early adversity with a specific visual threat-response pathway.

Sulfo-NHS-SS-Biotin: Practical Labeling Guide
2026-09-03
Sulfo-NHS-SS-Biotin provides water-compatible, amine-selective biotinylation with a cleavable disulfide spacer for affinity capture, detection, and label removal. It is appropriate for primary-amine-containing proteins and intact-cell surface workflows, but it should not be treated as a stable premixed solution or used without validation in samples containing competing amines or reduction-sensitive disulfides.

Early Life Adversity, Oxytocin, and Innate Defense
2026-08-25
Tan et al. report that early life adversity caused by postnatal social deprivation disrupts looming-evoked innate defensive behavior in mice through reduced oxytocin signaling in the superior colliculus. The study combines behavioral testing, receptor manipulation, circuit analysis, and intranasal oxytocin rescue to connect early experience with a specific threat-response pathway.

Biotin-tyramide A8011: TSA Workflow Guide
2026-08-22
Biotin-tyramide (SKU A8011) is a biotin phenol reagent for HRP-driven tyramide signal amplification in fixed-cell and tissue workflows, including immunohistochemistry and in situ hybridization. It is appropriate when localized signal enhancement is needed, but it requires solvent-aware preparation and assay-specific optimization; it should not be treated as a validated diagnostic reagent.

Comparative Gene Expression in Mammalian Claustrum
2026-08-21
The reference study proposes a cross-species framework for identifying conserved claustrum subdivisions by integrating gene expression, cytoarchitecture, and anatomical position. Its in situ hybridization analysis across rodents, shrews, and primates supports shared molecular and spatial organization despite major differences in brain size, while also clarifying the limits of translating mouse-based claustrum research.

Chemoproteomic SLC15A4 Inhibitors and Inflammation
2026-08-18
Chiu and colleagues used integrated chemical proteomics to develop functional small-molecule inhibitors of the endolysosomal transporter SLC15A4. The compounds suppressed TLR7–9 and NOD signaling across immune-cell systems and provided in vivo and patient-cohort evidence that SLC15A4 is a tractable target for autoimmune and autoinflammatory disease research.
