In the field of modern-day biotechnology, microsphere materials are extensively utilized in the extraction and filtration of DNA and RNA due to their high specific area, good chemical security and functionalized surface properties. Amongst them, polystyrene (PS) microspheres and their obtained polystyrene carboxyl (CPS) microspheres are among both most commonly examined and applied materials. This article is supplied with technological support and information evaluation by Shanghai Lingjun Biotechnology Co., Ltd., aiming to systematically compare the efficiency distinctions of these two types of materials in the process of nucleic acid removal, covering vital signs such as their physicochemical properties, surface area alteration ability, binding performance and healing price, and highlight their appropriate circumstances through experimental data.

Polystyrene microspheres are uniform polymer fragments polymerized from styrene monomers with good thermal stability and mechanical toughness. Its surface area is a non-polar framework and generally does not have active functional teams. For that reason, when it is directly used for nucleic acid binding, it needs to rely upon electrostatic adsorption or hydrophobic activity for molecular addiction. Polystyrene carboxyl microspheres present carboxyl functional groups (– COOH) on the basis of PS microspheres, making their surface with the ability of further chemical combining. These carboxyl groups can be covalently adhered to nucleic acid probes, healthy proteins or various other ligands with amino groups via activation systems such as EDC/NHS, thus attaining extra stable molecular fixation. Therefore, from an architectural viewpoint, CPS microspheres have extra advantages in functionalization capacity.

Nucleic acid extraction generally consists of actions such as cell lysis, nucleic acid launch, nucleic acid binding to strong stage providers, cleaning to get rid of pollutants and eluting target nucleic acids. In this system, microspheres play a core duty as strong stage service providers. PS microspheres mainly count on electrostatic adsorption and hydrogen bonding to bind nucleic acids, and their binding efficiency has to do with 60 ~ 70%, but the elution efficiency is low, just 40 ~ 50%. On the other hand, CPS microspheres can not only make use of electrostatic impacts but also attain more strong addiction via covalent bonding, minimizing the loss of nucleic acids throughout the washing procedure. Its binding efficiency can get to 85 ~ 95%, and the elution effectiveness is additionally raised to 70 ~ 80%. On top of that, CPS microspheres are also substantially much better than PS microspheres in terms of anti-interference ability and reusability.

In order to confirm the performance differences in between the two microspheres in actual operation, Shanghai Lingjun Biotechnology Co., Ltd. carried out RNA removal experiments. The speculative samples were derived from HEK293 cells. After pretreatment with standard Tris-HCl barrier and proteinase K, 5 mg/mL PS and CPS microspheres were utilized for extraction. The results revealed that the ordinary RNA yield drawn out by PS microspheres was 85 ng/ μL, the A260/A280 proportion was 1.82, and the RIN value was 7.2, while the RNA yield of CPS microspheres was increased to 132 ng/ μL, the A260/A280 proportion was close to the ideal value of 1.91, and the RIN worth got to 8.1. Although the operation time of CPS microspheres is a little longer (28 minutes vs. 25 minutes) and the cost is higher (28 yuan vs. 18 yuan/time), its extraction top quality is significantly enhanced, and it is preferable for high-sensitivity discovery, such as qPCR and RNA-seq.

From the point of view of application situations, PS microspheres appropriate for large-scale screening jobs and initial enrichment with low requirements for binding specificity due to their inexpensive and basic procedure. Nonetheless, their nucleic acid binding capability is weak and easily affected by salt ion concentration, making them unsuitable for lasting storage or repeated usage. On the other hand, CPS microspheres appropriate for trace sample removal as a result of their abundant surface practical teams, which promote further functionalization and can be utilized to create magnetic grain detection packages and automated nucleic acid extraction platforms. Although its preparation process is reasonably complex and the expense is fairly high, it reveals more powerful versatility in clinical research study and professional applications with rigorous requirements on nucleic acid extraction efficiency and purity.

With the quick advancement of molecular medical diagnosis, gene editing and enhancing, fluid biopsy and other fields, greater requirements are positioned on the efficiency, pureness and automation of nucleic acid removal. Polystyrene carboxyl microspheres are slowly replacing standard PS microspheres because of their exceptional binding efficiency and functionalizable qualities, becoming the core choice of a brand-new generation of nucleic acid removal materials. Shanghai Lingjun Biotechnology Co., Ltd. is also constantly maximizing the fragment dimension distribution, surface thickness and functionalization efficiency of CPS microspheres and developing matching magnetic composite microsphere items to fulfill the demands of medical diagnosis, clinical study establishments and commercial customers for premium nucleic acid removal solutions.
