In the field of modern-day biotechnology, microsphere products are commonly used in the removal and filtration of DNA and RNA due to their high certain surface area, great chemical stability and functionalized surface area buildings. Amongst them, polystyrene (PS) microspheres and their derived polystyrene carboxyl (CPS) microspheres are just one of both most extensively studied and applied materials. This article is provided with technological assistance and data evaluation by Shanghai Lingjun Biotechnology Co., Ltd., intending to systematically compare the efficiency distinctions of these 2 sorts of products in the procedure of nucleic acid removal, covering vital indications such as their physicochemical homes, surface area adjustment ability, binding performance and recovery price, and illustrate their relevant scenarios through speculative data.
Polystyrene microspheres are homogeneous polymer particles polymerized from styrene monomers with good thermal security and mechanical toughness. Its surface area is a non-polar framework and usually does not have energetic functional groups. As a result, when it is straight used for nucleic acid binding, it requires to depend on electrostatic adsorption or hydrophobic action for molecular addiction. Polystyrene carboxyl microspheres present carboxyl practical teams (– COOH) on the basis of PS microspheres, making their surface area 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 through activation systems such as EDC/NHS, thus accomplishing more stable molecular addiction. As a result, from a structural perspective, CPS microspheres have much more advantages in functionalization potential.
Nucleic acid extraction typically includes steps such as cell lysis, nucleic acid launch, nucleic acid binding to strong phase providers, washing to remove impurities and eluting target nucleic acids. In this system, microspheres play a core duty as solid stage providers. PS microspheres mainly count on electrostatic adsorption and hydrogen bonding to bind nucleic acids, and their binding effectiveness has to do with 60 ~ 70%, however the elution efficiency is reduced, just 40 ~ 50%. On the other hand, CPS microspheres can not just make use of electrostatic impacts yet also achieve even more strong addiction via covalent bonding, reducing the loss of nucleic acids during the washing process. Its binding effectiveness can reach 85 ~ 95%, and the elution efficiency is likewise boosted to 70 ~ 80%. Furthermore, CPS microspheres are additionally considerably far better than PS microspheres in terms of anti-interference capability and reusability.
In order to confirm the efficiency distinctions in between the two microspheres in actual procedure, Shanghai Lingjun Biotechnology Co., Ltd. performed RNA extraction experiments. The experimental examples were derived from HEK293 cells. After pretreatment with standard Tris-HCl buffer and proteinase K, 5 mg/mL PS and CPS microspheres were made use of for removal. The results showed that the ordinary RNA return extracted by PS microspheres was 85 ng/ μL, the A260/A280 proportion was 1.82, and the RIN value was 7.2, while the RNA return of CPS microspheres was increased to 132 ng/ μL, the A260/A280 proportion was close to the optimal value of 1.91, and the RIN worth reached 8.1. Although the procedure time of CPS microspheres is a little longer (28 minutes vs. 25 minutes) and the expense is higher (28 yuan vs. 18 yuan/time), its removal quality is substantially enhanced, and it is better 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 jobs and preliminary enrichment with low requirements for binding specificity as a result of their affordable and straightforward operation. However, their nucleic acid binding capacity is weak and easily affected by salt ion focus, making them unsuitable for long-lasting storage space or duplicated use. In contrast, CPS microspheres appropriate for trace example extraction due to their rich surface area practical teams, which help with further functionalization and can be used to build magnetic grain detection kits and automated nucleic acid extraction platforms. Although its preparation procedure is fairly intricate and the cost is fairly high, it shows more powerful flexibility in scientific study and medical applications with rigorous needs on nucleic acid extraction efficiency and purity.
With the quick development of molecular medical diagnosis, genetics editing and enhancing, fluid biopsy and various other areas, higher needs are positioned on the performance, pureness and automation of nucleic acid extraction. Polystyrene carboxyl microspheres are gradually changing traditional PS microspheres because of their outstanding binding performance and functionalizable characteristics, ending up being the core choice of a brand-new generation of nucleic acid extraction materials. Shanghai Lingjun Biotechnology Co., Ltd. is additionally constantly maximizing the fragment size distribution, surface density and functionalization effectiveness of CPS microspheres and developing matching magnetic composite microsphere products to fulfill the needs of clinical medical diagnosis, scientific study institutions and industrial clients for high-grade nucleic acid extraction solutions.
