(LNJNbio Polystyrene Microspheres)

In the field of contemporary biotechnology, microsphere materials are widely used in the extraction and filtration of DNA and RNA due to their high certain area, great chemical stability and functionalized surface area homes. Amongst them, polystyrene (PS) microspheres and their obtained polystyrene carboxyl (CPS) microspheres are among both most commonly examined and applied materials. This article is provided with technical assistance and data evaluation by Shanghai Lingjun Biotechnology Co., Ltd., aiming to methodically contrast the performance differences of these two types of products in the procedure of nucleic acid removal, covering key indications such as their physicochemical properties, surface area modification capacity, binding performance and recuperation rate, and illustrate their relevant scenarios through experimental data.

Polystyrene microspheres are homogeneous polymer fragments polymerized from styrene monomers with great thermal stability and mechanical toughness. Its surface is a non-polar framework and usually does not have active practical teams. As a result, when it is straight used for nucleic acid binding, it requires to count on electrostatic adsorption or hydrophobic activity for molecular fixation. Polystyrene carboxyl microspheres present carboxyl practical groups (– COOH) on the basis of PS microspheres, making their surface area capable of further chemical combining. These carboxyl teams can be covalently bound to nucleic acid probes, proteins or various other ligands with amino groups with activation systems such as EDC/NHS, therefore accomplishing more steady molecular addiction. As a result, from an architectural point of view, CPS microspheres have extra benefits in functionalization possibility.

Nucleic acid extraction typically includes steps such as cell lysis, nucleic acid release, nucleic acid binding to strong phase providers, cleaning to get rid of pollutants and eluting target nucleic acids. In this system, microspheres play a core function as strong phase providers. PS microspheres mostly rely upon electrostatic adsorption and hydrogen bonding to bind nucleic acids, and their binding efficiency is about 60 ~ 70%, but the elution efficiency is reduced, just 40 ~ 50%. On the other hand, CPS microspheres can not only use electrostatic effects yet additionally accomplish even more strong addiction with covalent bonding, reducing the loss of nucleic acids throughout the cleaning process.

The speculative samples were stemmed from HEK293 cells. After pretreatment with common 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 extracted 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 enhanced to 132 ng/ μL, the A260/A280 proportion was close to the suitable value of 1.91, and the RIN value got to 8.1. Although the operation time of CPS microspheres is somewhat longer (28 mins vs. 25 mins) and the cost is greater (28 yuan vs. 18 yuan/time), its extraction quality is dramatically improved, and it is better for high-sensitivity detection, such as qPCR and RNA-seq.
