Product Overview
Trichloroacetic Acid (TCA) LR grade is a highly pure crystalline powder designed for demanding laboratory applications. Known for its strong acidic properties, this reagent is widely utilized in biochemical processes, particularly for protein precipitation, where it effectively denatures and aggregates proteins for downstream analysis. Its high solubility in water and organic solvents makes it versatile for various experimental setups, including tissue fixation and nucleic acid extraction protocols. The LR grade ensures minimal impurities, providing consistent and reliable results in sensitive assays. With a molecular formula of C2HCl3O2, this compound delivers precise performance in analytical and preparative workflows. Proper handling and storage are essential due to its corrosive nature, ensuring long-term stability and safety in lab environments. Whether used in qualitative or quantitative analysis, this TCA variant meets the stringent requirements of modern research laboratories, offering reproducibility and accuracy in critical procedures.
FAQs
1. What is the shelf life of Trichloroacetic Acid LR when stored properly?
When stored in a tightly sealed container away from moisture and light, Trichloroacetic Acid LR retains its stability for up to 24 months from the date of manufacture. Always check the label for specific expiration details.
2. Can this grade of TCA be used for DNA precipitation?
While primarily used for protein precipitation, LR-grade Trichloroacetic Acid can also assist in nucleic acid precipitation when combined with appropriate protocols, though specialized reagents may be preferred for DNA-specific applications.
3. Is this product compatible with plastic labware?
Trichloroacetic Acid is corrosive and may degrade certain plastics over time. For long-term storage or reactions, use glass or chemically resistant containers like PP or HDPE to avoid contamination.
4. What safety precautions should be taken while handling this acid?
Always wear protective gear, including gloves, goggles, and a lab coat, when handling TCA. Work in a fume hood to avoid inhaling vapors, and neutralize spills immediately with a suitable base like sodium bicarbonate.
5. Are there any alternatives to TCA for protein precipitation?
Alternatives like sulfosalicylic acid or acetone can be used depending on the experimental requirements, though TCA remains a standard due to its efficiency and minimal interference in downstream applications.
