CheKine™ Micro Hydroxyl Free Radical Scavenging Capacity Assay Kit: The Gold Standard for •OH Scavenging Studies
The Hydroxyl Radical: The Most Damaging ROS The hydroxyl radical (•OH) is the most reactive and damaging of all reactive oxygen species. It reacts indiscriminately with lipids, proteins, and DNA at diffusion-limited rates. Measuring •OH scavenging capacity is therefore essential for evaluating the antioxidant potential of compounds, extracts, and biological samples. Why Abbkine KTB1091 Stands Out Feature Abbkine KTB1091 Traditional •OH Scavenging Assays Detection Method Salicylic Acid Method (520 nm)[reference:107] Variable; often complex Sample Types Animal/plant tissues, serum, plasma, cells, bacteria, supernatant, juice, honey, urine[reference:108] Limited compatibility Sensitivity High; detects •OH scavenging capacity accurately[reference:109] Variable Protocol Simple, convenient[reference:110] Often multi-step, time-consuming Storage 12 months at 4°C[reference:111] Shorter shelf life Publications 2 citations[reference:112] Fewer The Fenton Reaction Principle The assay is…
CheKine™ Micro Superoxide Anion Scavenging Capacity Assay Kit: A Buyer's Guide
