How to Choose the Right Merck Biochemicals — Frequently Asked Questions
Selecting the best biochemical reagents is crucial for successful, reproducible experiments. To help you make informed decisions, we’ve compiled answers to the most common questions about product selection, purity standards, and technical documentation for Merck Biochemicals.
Consider your application’s pH requirements, ionic strength, and compatibility with other reagents. Merck offers a wide range of buffers, such as Phosphate Buffer Saline (PBS) P4417 for general cell work or Tris-HCl Buffer T5941 for molecular biology. Review each buffer’s technical datasheet to match its properties with your protocol needs.
Q2: What factors should I consider when selecting a detergent?The choice depends on whether you need to solubilize membrane proteins, lyse cells, or remove contaminants. For gentle extraction, Triton X-100 (T9284) is widely used, while stronger detergents like SDS (L3771) suit more robust lysis. Always confirm compatibility with your downstream applications.
Q3: How can I verify the purity and grade of a biochemical reagent?Purity specifications are listed in each product’s Certificate of Analysis (COA) and technical data sheet. Merck biochemicals are available in research and analytical grades, with high-purity options for sensitive assays. Refer to documentation linked on the product page, or request a COA for batch-specific details.
Q4: Where can I find batch information and documentation for Merck biochemicals?Each product page provides downloadable COA, MSDS, and technical datasheets. For specific batch information, enter the lot number on Merck’s website or contact technical support for rapid assistance.
Q5: How do I select antibiotics for cell culture or selection protocols?Choose an antibiotic based on your cell type, target organism, and selection marker. For example, Kanamycin Sulfate (K8753) is ideal for bacterial selection, while G418 Sulfate (A1720) is commonly used for mammalian cells. Confirm concentration and application details with the product’s datasheet.
