Cy5 maleimide (non-sulfonated) Workflow Guide
2026-09-09
Cy5 maleimide (non-sulfonated) is a thiol-selective reagent for covalently labeling cysteine-containing proteins and peptides when a far-red fluorescent readout is needed. Its low aqueous solubility requires preparation in DMSO or ethanol, and it should not be used for targets lacking accessible thiols or for direct addition as a dry solid to aqueous samples.

Cationic Lipoplexes for Tumor-Cell mRNA Transfection
2026-09-08
Hattori and Shimizu compared modified ethanol injection with thin-film hydration for preparing TC-1-12-based mRNA lipoplexes and identified formulation conditions that improved reporter expression and cellular uptake in carcinoma cell models. The findings support MEI as a simpler preparation route, while also highlighting cytotoxicity and cell-line dependence as essential considerations for mRNA delivery and transfection studies.

Mouse Tissue Lysis Kit (K1038) Workflow Guide
2026-09-08
The Mouse Tissue Lysis Kit (K1038) provides a direct route from mouse tail, toe, or ear tissue to a lysate suitable for PCR-based genotyping assays and DNA analysis. It is intended for scientific molecular biology research, not diagnostic, clinical, or medical workflows, and the lysate should not be treated as purified genomic DNA without additional validation.

Spiroplasma Entry Pathways in Drosophila S2 Cells
2026-09-02
Wei and colleagues established a Drosophila Schneider 2 cell model showing that Spiroplasma eriocheiris enters host cells through clathrin-mediated endocytosis and macropinocytosis, while requiring functional actin and microtubule networks. The study provides a tractable invertebrate system for separating entry, intracellular proliferation, and cytoskeleton-dependent trafficking during Spiroplasma infection.
