• Cy7 NHS Ester: Practical Labeling Guide

  2026-09-20

  Cy7 NHS ester (SKU A8109) is a water-soluble near-infrared dye for bioimaging that enables amino-group labeling of proteins and peptides without requiring an organic co-solvent. It is suited to carefully controlled in vitro and exploratory in vivo workflows, but not to targets lacking accessible amino groups or long-term storage of prepared dye solutions.

• PreScission Protease (PSP): Practical Tag Cleavage

  2026-09-19

  PreScission Protease (PSP) is an HRV 3C protease fusion enzyme for sequence-directed removal of affinity tags from recombinant proteins. It is appropriate when the defined LEVLFQGP cleavage sequence is present and cold processing is acceptable, but it should not be treated as a general-purpose protease or applied without construct-specific validation.

• Allosteric Biosensor Tracks Endogenous Protein Dynamics

  2026-09-15

  The reference study introduces Step, an allosteric genetically encoded biosensor designed to visualize endogenous protein abundance, localization, and relocalization in living cells without directly modifying the target protein. Its circStep implementation converts a single protein–aptamer recognition event into activation of dual fluorogenic RNA aptamers, creating a low-background platform for real-time imaging and drug-relocation screening.

• N2-Alkyl-dG Lesions and R-Loop Accumulation

  2026-09-14

  The reference study shows that minor-groove N2-alkyl-dG DNA lesions promote R-loop accumulation in chromatin and plasmid DNA, linking alkylation damage to impaired transcription elongation and genome instability. Its combined imaging, R-loop sequencing, and genetic perturbation strategy provides a framework for studying how DNA adducts reshape transcription-associated nucleic acid structures.

• GPR35–KLF5 Signaling in Intestinal Epithelial Repair

  2026-09-14

  The reference study identifies a tryptophan–kynurenine–kynurenic acid metabolic gate in which GPR35 detects mucosal damage and signals through KLF5 and PI3K–AKT–mTOR to coordinate epithelial proliferation and migration. This framework connects metabolite sensing with epithelial repair and provides a mechanistic basis for interpreting barrier restoration in ulcerative colitis research and intestinal inflammation models.

• β-Pseudouridine in saRNA Assay Design
