SmD2 Acetylation Links Splicing to PARP Response in HCC
2026-09-25
This study links acetylation-dependent control of the core spliceosome protein SmD2 to BRCA1/FANC cassette-exon regulation, DNA damage repair, and PARP-inhibitor sensitivity in hepatocellular carcinoma. It also reports preclinical potential for combining the HDAC inhibitor romidepsin with olaparib, while leaving questions about patient selection and clinical translation open.

Propidium iodide: Practical Assay Decisions
2026-09-25
This scenario-driven guide explains how Propidium iodide (SKU B7758) can support membrane-integrity, apoptosis, and cell-cycle workflows—and where its readout needs careful interpretation. It connects product handling details with experimental controls and a recent electroporation study, without treating PI as a substitute for metabolic or impedance-based measurements.

Live-Dead Cell Staining Kit I: Calcein AM/PI
2026-09-24
The Live-Dead Cell Staining Kit I uses Calcein AM and propidium iodide (PI) to distinguish viable from membrane-compromised mammalian cells by fluorescence. This Calcein AM/PI staining kit supports cell viability and cytotoxicity assays, but it is not suitable for staining bacteria or fungi.

Trichostatin A: Practical Workflows for Cancer Research
2026-09-24
Use Trichostatin A (TSA) to test how HDAC inhibition reshapes histone acetylation, cell-cycle behavior, and differentiation in cultured-cell models. This workflow-focused guide separates product-reported findings from recommended pilot conditions and connects TSA experiments to a distinct senescence study without implying that the study tested TSA.

CA-074 Me: Cathepsin B Inhibitor for Cell Studies
2026-09-23
CA-074 Me is a cell-permeable cathepsin B inhibitor used to test how intracellular cathepsin B contributes to lysosomal pathways and cell death. Its selectivity has an important boundary: product information reports partial cathepsin L inhibition under reducing conditions, so orthogonal controls are important when interpreting results.

HyperPFU™ high-fidelity DNA polymerase Guide
2026-09-23
HyperPFU™ high-fidelity DNA polymerase is intended for accurate amplification of long, GC-rich, inhibitor-affected, or otherwise difficult DNA templates. It produces blunt-ended PCR products for compatible cloning and sequencing workflows, but it should not be selected when 3′-A overhangs or preformed sticky ends are required.

PLK1 Control of p31comet in Mitotic Checkpoint Exit
2026-09-21
Kaisari et al. identify a regulatory connection between PLK1 and p31comet, showing that PLK1 phosphorylation at S102 suppresses p31comet–TRIP13-mediated disassembly of mitotic checkpoint complexes. The work provides a mechanistic explanation for how an active spindle checkpoint may prevent premature MCC disassembly and offers a framework for interpreting BI 2536-based PLK1 perturbation experiments.

HyperPFU™ high-fidelity DNA polymerase Guide
2026-09-21
HyperPFU™ high-fidelity DNA polymerase is a proofreading DNA polymerase for accurate amplification of long, GC-rich, inhibitor-affected, or otherwise difficult templates. It is suited to blunt-ended products for cloning and sequencing, but not to workflows that require 3′-A overhangs or polymerase-generated sticky ends.
