- World’s cleanest RNase-safe buffer for RNA handling, cell, and molecular biology experiments
Description:
PVSA-MOPS, 1X is a ready-to-use, high-purity MOPS buffer formulated to be RNase-safe for sensitive RNA and DNA workflows in the near-neutral pH range. 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 the well-defined buffering characteristics of 1X MOPS at physiological pH, 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 nucleic acids in a MOPS-based buffer with added RNase protection for storage or downstream analysis.
- RNA Handling and Short-Term Storage: Temporary storage of RNA-containing samples, lysates, or purified RNA where a zwitterionic, near-neutral buffer is preferred.
- Sample Preparation for Enzymatic Assays: Handling and transfer of nucleic acids prior to downstream applications (e.g., RT, qPCR, library prep), as compatible with enzyme- and salt-specific requirements.
- Cell and Tissue Processing: Buffering solution for gentle handling or washing of cells and tissues in workflows where RNA integrity is important and MOPS is specified.
- General Molecular Biology: Any procedure requiring 1X MOPS with enhanced RNA protection under controlled, near-physiological pH conditions.
Advantages:
- RNase-Safe: PVSA provides robust inhibition of a broad range of RNases, complementing nuclease-free techniques and reducing reliance on protein-based inhibitors.
- High Purity: Manufactured from molecular biology-grade MOPS and PVSA and finely filtered to minimize particulates, microbial contamination, and adventitious nucleases.
- Versatile Usage: Compatible with protocols that specify MOPS as the buffering system for RNA or protein-adjacent workflows.
- Ready-to-Use 1X Solution: Supplied at working strength to reduce preparation time, variability, and contamination risk.
