Product Overview
BIAL’S REAGENT (SUMNER) is a specialized laboratory reagent formulated for the qualitative detection of pentose sugars in biochemical samples. This reagent, developed based on Sumner’s formulation, reacts with pentoses to produce a characteristic green-blue color, facilitating easy identification. The liquid form ensures uniform mixing and consistent results in analytical procedures. Designed for laboratory use, it maintains high purity and stability under standard storage conditions, making it ideal for routine biochemical testing. The reagent’s composition includes orcinol and concentrated hydrochloric acid, which together enable selective pentose detection without interference from hexoses or other carbohydrates. Its reliability and ease of use make it a preferred choice for researchers and lab technicians conducting carbohydrate analysis. Proper handling and storage are essential to maintain its efficacy, as exposure to moisture or contaminants may compromise performance. For optimal results, follow standard laboratory protocols when using this reagent in qualitative assays.
FAQs
1. What is the shelf life of Bial’s Reagent (Sumner) when stored properly?
The reagent typically retains its efficacy for 12–24 months when stored in a cool, dry place away from direct sunlight and moisture. Always check the label for the manufacturer’s recommended expiry date.
2. Can this reagent detect other sugars besides pentoses?
Bial’s Reagent is specifically formulated for pentose sugars and may not reliably detect hexoses or disaccharides. Cross-reactivity with non-pentose compounds is minimal under standard testing conditions.
3. What precautions should be taken while handling this reagent?
The reagent contains concentrated hydrochloric acid, so wear protective gloves, goggles, and a lab coat. Avoid inhalation or skin contact, and use it in a well-ventilated area or fume hood.
4. Is this reagent compatible with automated lab systems?
While primarily designed for manual testing, it can be adapted for semi-automated systems if the reagent volume and reaction conditions are precisely controlled. Consult your equipment manual for compatibility guidelines.
5. How should discarded Bial’s Reagent be disposed of?
Neutralize the reagent with a suitable base (e.g., sodium bicarbonate) before disposal, following local hazardous waste regulations. Never pour untreated reagent down drains or into regular trash.
