IgSF6, ER Stress, and Antibacterial Macrophages
2026-09-10
This 2024 Mucosal Immunology study identifies the endoplasmic-reticulum-localized immunoglobulin IgSF6 as a regulator of intestinal macrophage stress responses. Loss of Igsf6 strengthened IRE1α–XBP1 signaling, reactive oxygen species production, inflammation, and bacterial killing, but increased susceptibility to DSS-induced colitis, revealing a context-dependent tradeoff between host defense and intestinal homeostasis.

Cy5 maleimide (non-sulfonated): Labeling Guide
2026-09-10
Cy5 maleimide (non-sulfonated) is a thiol-reactive fluorophore for covalent labeling of accessible cysteine residues in peptides and proteins. It is appropriate when site-selective fluorescence labeling is needed, but its low aqueous solubility makes it unsuitable for direct addition as a solid to aqueous samples.

CLCC1 and Herpesvirus Nuclear Egress
2026-09-09
A bioRxiv study identifies the host protein CLCC1 as an essential factor in the membrane-fusion step of herpesvirus nuclear egress. By combining a whole-genome CRISPR screen with cellular and virological analyses, the work links CLCC1 loss to perinuclear capsid accumulation, impaired nuclear pore insertion, and reduced HSV-1 production.

BX795: Separating Signaling from Cell Killing
2026-09-09
BX795 is a PDK1 inhibitor with additional TBK1 and IKKε activity. This guide shows how to pair its signaling effects with response-aware viability measurements so cancer and innate immune assays distinguish pathway suppression from true cell death.

Merbromin BA1653 for Reliable Assay Design
2026-09-08
Learn how Merbromin (SKU BA1653) can support reproducible fluorescence, absorbance, protein-binding, and enzyme-inhibition workflows without being mistaken for a conventional cell-viability dye. The article translates validated spectroscopic data into practical guidance for experimental design, optimization, interpretation, and product selection.

Canagliflozin Hemihydrate: Research Workflows
2026-09-08
Use Canagliflozin hemihydrate to interrogate renal glucose reabsorption inhibition, glucose homeostasis, and diabetes-related phenotypes with a workflow that separates SGLT2 biology from mTOR effects. A drug-sensitized yeast study adds a valuable counter-screening strategy and shows why a clean negative TOR result can strengthen pathway interpretation.

LDH Cytotoxicity Assay Kit: Practical Workflow
2026-09-07
The LDH Cytotoxicity Assay Kit supports cell cytotoxicity measurement by quantifying LDH released into culture medium after loss of membrane integrity. It is appropriate for comparative cell damage studies, but should not be used alone to identify apoptosis or establish a specific death mechanism.

Propidium Iodide in Immune-Cell Assays
2026-09-07
Propidium iodide is more than a routine viability stain: it provides a membrane-integrity endpoint that can sharpen interpretation of trophoblast–immune cell experiments. This guide connects PI chemistry, apoptosis and cell-cycle workflows, and recent preeclampsia research to improve assay design and biological inference.

Caspase-3 Colorimetric Assay Kit: Workflow Guide
2026-09-05
The Caspase-3 Colorimetric Assay Kit measures DEVD-dependent caspase-3 activity in biological samples through cleavage of a chromogenic substrate and detection of liberated p-nitroaniline. It is suitable for lysate-based apoptosis assays and caspase activity measurement, but not for in vivo imaging, direct protein-abundance measurement, or definitive assignment of all DEVD cleavage to caspase-3.

Separating Growth Arrest from Cell Death in Cancer Assays
2026-09-04
Hannah R. Schwartz’s dissertation identifies a major interpretive problem in anticancer drug testing: relative viability and fractional viability are often treated as interchangeable even though they measure different biological outcomes. The work supports paired, time-aware measurements that distinguish cancer cell proliferation inhibition from actual cell killing, improving how in vitro drug responses are interpreted.

ALDOB K87 Lactylation in Pulmonary Hypertension
2026-09-03
The reference study identifies ALDOB K87 lactylation as a metabolic–mitochondrial link in pulmonary hypertension, connecting hypoxia-driven lactate accumulation with DRP1-dependent mitochondrial fission and pulmonary artery smooth muscle cell remodeling. Its integrated lactylomic, cellular, and animal experiments provide a framework for separating metabolic mechanisms from nonspecific mitogenic effects in follow-up assays.

CFDA-SE for Proliferation and CD38 Migration Studies
2026-09-03
CFDA-SE converts intracellular esterase activity into a division-resolved fluorescence record for lymphocytes, fibroblasts, NK cells, bacteria, and migrating populations. Used alongside CD38 proximity proteomics, it adds functional proliferation history without confusing cell division with direct protein association.
