- World’s cleanest RNase-safe buffer for RNA handling, cell, and molecular biology experiments
Description:
PVSA-Tris-HCl, 1X is a ready-to-use, high-purity Tris-HCl buffer formulated to be RNase-safe for sensitive RNA and DNA workflows. It is supplemented with polyvinylsulfonic acid (PVSA), a potent polymeric RNase inhibitor that helps preserve RNA integrity during sample handling, processing, and short-term storage. The buffer provides a well-defined, near-physiological pH environment characteristic of 1X Tris-HCl, making it suitable for use with purified nucleic acids, RNA-containing samples, and cells in downstream molecular biology applications.
Applications:
- RNA and DNA Resuspension: Resuspension and dilution of RNA and DNA samples in a defined Tris-HCl buffer with added RNase protection.
- RNA Handling and Short-Term Storage: Temporary storage of RNA-containing samples, lysates, or purified RNA in an RNase-controlled environment.
- Sample Preparation for Enzymatic Assays: Handling and transfer of nucleic acids prior to downstream applications (e.g., RT, PCR, qPCR, library prep), as compatible with specific enzyme and salt requirements.
- Cell and Tissue Processing: Buffering solution for gentle handling or washing of cells and tissues in workflows where RNA integrity is important.
- General Molecular Biology: Any procedure requiring 1X Tris-HCl with enhanced RNA protection in low-to-moderate ionic strength conditions.
Advantages:
- RNase-Safe: PVSA provides robust inhibition of a broad range of RNases, complementing best practices and reducing reliance on protein-based inhibitors.
- High Purity: Prepared from molecular biology-grade Tris and PVSA, and finely filtered to minimize particulates, microbial load, and adventitious nucleases.
- Stable pH Environment: Tris-HCl buffering capacity helps maintain a consistent pH during routine sample handling steps.
- Versatile Usage: Compatible with many standard nucleic acid handling and preparation protocols that call for Tris-based buffers.
- Ready-to-Use 1X Solution: Supplied at working strength to reduce preparation time, variability, and contamination risk.
