Area of Science:

• Biomaterials Science
• Molecular Biology
• Biochemistry

Background:

• Ribonucleic acid (RNA) isolation and purification are critical for understanding cellular functions and developing treatments for genetic diseases.
• Current purification methods require optimization for efficiency and specificity.

Purpose of the Study:

• To develop guanine-incorporated polymeric cryogels for highly purified ribonucleic acid (RNA) isolation.
• To investigate the natural interaction between guanine monomers and cytosine in RNA for enhanced purification.

Main Methods:

• Synthesis of poly(2-hydroxyethyl methacrylate-guanine methacrylate) cryogels.
• Characterization of cryogel properties, including porosity and swelling ratio.
• Evaluation of chromatographic separation performance under various conditions (pH, temperature).
• Analysis of adsorption-desorption cycles for reusability.

Main Results:

• Guanine-incorporated cryogels demonstrated satisfactory purification performance for RNA.
• A natural interaction between guanine on the cryogel and cytosine on RNA was confirmed.
• The porous cryogel structure facilitated efficient and fast RNA adsorption.
• Cryogels maintained performance over five adsorption-desorption cycles, indicating good reusability.

Conclusions:

• Guanine-incorporated polymeric cryogels are effective for high-purity RNA isolation.
• The specific guanine-cytosine interaction enhances purification efficiency.
• These cryogels offer a reusable and efficient platform for RNA purification in genetic research.
