Guanidine salts—more compatible! Leading Medical’s new patent tackles the “bottleneck” challenge in viral preservation solutions.

Recently, Leading Medical has been granted another invention patent! A non-guanidinium salt–based viral preservation solution compatible with nucleic acid extraction, along with its preparation method and applications. By establishing a novel non-guanidine‑salt technology platform, we have addressed the key pain points of conventional guanidine‑salt formulations, delivering a more stable and highly compatible sample‑preservation solution.

Technological Breakthrough: Comprehensive Optimization of the Novel Non-Guanidinium Salt System
Leading Medical uses P(HEMA‑BAMPD hydrochloride) as its core ingredient, combined with buffers, chelating agents, and carbohydrate stabilizers. Through electrostatic adsorption and hydrogen bonding, it protects viral nucleic acids, inhibits nuclease activity, and maintains an isotonic environment, thereby achieving efficient inactivation and stable preservation.

Core Advantages:

Dimension	Traditional guanidinium salt system	Lidin non-guanidine salt system
Nucleic acid extraction compatibility	⭐⭐	⭐⭐⭐⭐⭐
RNA stability	⭐⭐	⭐⭐⭐⭐⭐
Resistance to organic interference	⭐⭐	⭐⭐⭐⭐⭐
Suitable for long-term storage and transportation	⭐⭐	⭐⭐⭐⭐⭐

Application scenarios: Third-party medical laboratories, disease control centers, cross-border and interregional sample transportation, and automated nucleic acid extraction platforms.
