In the field of modern-day biotechnology, microsphere materials are commonly made use of in the removal and filtration of DNA and RNA as a result of their high certain area, good chemical security and functionalized surface homes. Among them, polystyrene (PS) microspheres and their acquired polystyrene carboxyl (CPS) microspheres are just one of the two most extensively studied and applied materials. This post is offered with technical support and information evaluation by Shanghai Lingjun Biotechnology Co., Ltd., aiming to methodically compare the efficiency distinctions of these 2 types of products in the procedure of nucleic acid removal, covering crucial indications such as their physicochemical residential properties, surface area alteration capability, binding effectiveness and recuperation rate, and show their suitable circumstances with speculative data.
Polystyrene microspheres are uniform polymer particles polymerized from styrene monomers with excellent thermal security and mechanical strength. Its surface area is a non-polar framework and usually does not have active functional groups. For that reason, when it is directly used for nucleic acid binding, it requires to rely upon electrostatic adsorption or hydrophobic action for molecular addiction. Polystyrene carboxyl microspheres introduce carboxyl practical groups (– COOH) on the basis of PS microspheres, making their surface capable of more chemical coupling. These carboxyl teams can be covalently bonded to nucleic acid probes, healthy proteins or other ligands with amino groups with activation systems such as EDC/NHS, thus achieving a lot more steady molecular fixation. For that reason, from a structural point of view, CPS microspheres have more advantages in functionalization capacity.
Nucleic acid extraction typically includes actions such as cell lysis, nucleic acid launch, nucleic acid binding to strong stage service providers, cleaning to remove impurities and eluting target nucleic acids. In this system, microspheres play a core function as strong stage service providers. PS microspheres generally depend on electrostatic adsorption and hydrogen bonding to bind nucleic acids, and their binding effectiveness is about 60 ~ 70%, however the elution effectiveness is reduced, only 40 ~ 50%. On the other hand, CPS microspheres can not just use electrostatic results yet additionally attain more solid addiction via covalent bonding, lowering the loss of nucleic acids during the washing process. Its binding efficiency can get to 85 ~ 95%, and the elution efficiency is also raised to 70 ~ 80%. Additionally, CPS microspheres are also substantially much better than PS microspheres in terms of anti-interference capacity and reusability.
In order to confirm the efficiency distinctions between both microspheres in actual procedure, Shanghai Lingjun Biotechnology Co., Ltd. performed RNA removal experiments. The speculative examples were originated from HEK293 cells. After pretreatment with typical Tris-HCl barrier and proteinase K, 5 mg/mL PS and CPS microspheres were used for removal. The results revealed that the average RNA yield drawn out by PS microspheres was 85 ng/ μL, the A260/A280 ratio was 1.82, and the RIN worth was 7.2, while the RNA yield of CPS microspheres was boosted to 132 ng/ μL, the A260/A280 proportion was close to the ideal worth of 1.91, and the RIN value got to 8.1. Although the operation time of CPS microspheres is slightly longer (28 minutes vs. 25 mins) and the cost is greater (28 yuan vs. 18 yuan/time), its removal top quality is dramatically improved, and it is more suitable for high-sensitivity detection, such as qPCR and RNA-seq.

From the point of view of application situations, PS microspheres appropriate for large-scale screening tasks and initial enrichment with reduced needs for binding uniqueness due to their affordable and easy procedure. Nevertheless, their nucleic acid binding capacity is weak and easily affected by salt ion concentration, making them unsuitable for long-lasting storage or duplicated usage. In contrast, CPS microspheres are suitable for trace example removal because of their rich surface useful teams, which help with more functionalization and can be used to build magnetic bead detection sets and automated nucleic acid removal platforms. Although its prep work process is reasonably complicated and the expense is fairly high, it shows stronger flexibility in scientific research study and professional applications with strict needs on nucleic acid extraction performance and purity.
With the fast development of molecular medical diagnosis, gene editing, liquid biopsy and various other areas, higher requirements are positioned on the effectiveness, purity and automation of nucleic acid removal. Polystyrene carboxyl microspheres are gradually replacing conventional PS microspheres as a result of their exceptional binding performance and functionalizable characteristics, becoming the core option of a new generation of nucleic acid extraction materials. Shanghai Lingjun Biotechnology Co., Ltd. is likewise continually enhancing the particle size circulation, surface thickness and functionalization efficiency of CPS microspheres and developing matching magnetic composite microsphere items to meet the needs of medical diagnosis, clinical research institutions and industrial consumers for high-grade nucleic acid extraction options.
