(LNJNbio Polystyrene Microspheres)

In the area of modern biotechnology, microsphere products are commonly made use of in the removal and purification of DNA and RNA due to their high specific area, great chemical stability and functionalized surface area properties. Amongst them, polystyrene (PS) microspheres and their acquired polystyrene carboxyl (CPS) microspheres are one of both most commonly examined and applied materials. This post is supplied with technological support and data evaluation by Shanghai Lingjun Biotechnology Co., Ltd., intending to systematically contrast the performance differences of these 2 sorts of products in the procedure of nucleic acid extraction, covering key signs such as their physicochemical residential properties, surface adjustment ability, binding effectiveness and healing rate, and illustrate their suitable situations through speculative information.

Polystyrene microspheres are uniform polymer fragments polymerized from styrene monomers with excellent thermal stability and mechanical stamina. Its surface area is a non-polar framework and typically does not have active functional teams. Consequently, when it is straight made use of for nucleic acid binding, it needs to rely upon electrostatic adsorption or hydrophobic action for molecular addiction. Polystyrene carboxyl microspheres introduce carboxyl useful groups (– COOH) on the basis of PS microspheres, making their surface efficient in additional chemical coupling. These carboxyl teams can be covalently bound to nucleic acid probes, healthy proteins or various other ligands with amino teams with activation systems such as EDC/NHS, therefore achieving a lot more steady molecular addiction. For that reason, from an architectural point of view, CPS microspheres have extra advantages in functionalization potential.

Nucleic acid extraction generally consists of actions such as cell lysis, nucleic acid launch, nucleic acid binding to solid phase carriers, washing to get rid of contaminations and eluting target nucleic acids. In this system, microspheres play a core function as solid stage carriers. PS microspheres mainly rely on electrostatic adsorption and hydrogen bonding to bind nucleic acids, and their binding effectiveness has to do with 60 ~ 70%, yet the elution efficiency is reduced, just 40 ~ 50%. On the other hand, CPS microspheres can not just use electrostatic effects yet also attain more strong addiction via covalent bonding, reducing the loss of nucleic acids throughout the cleaning procedure. Its binding effectiveness can reach 85 ~ 95%, and the elution performance is additionally raised to 70 ~ 80%. On top of that, CPS microspheres are likewise substantially better than PS microspheres in terms of anti-interference ability and reusability.

In order to confirm the performance differences between the two microspheres in real procedure, Shanghai Lingjun Biotechnology Co., Ltd. carried out RNA extraction experiments. The speculative examples were originated from HEK293 cells. After pretreatment with typical Tris-HCl buffer and proteinase K, 5 mg/mL PS and CPS microspheres were made use of for extraction. The results revealed that the ordinary RNA yield drawn out by PS microspheres was 85 ng/ μL, the A260/A280 ratio was 1.82, and the RIN value was 7.2, while the RNA yield of CPS microspheres was enhanced to 132 ng/ μL, the A260/A280 ratio was close to the optimal worth of 1.91, and the RIN worth got to 8.1. Although the operation time of CPS microspheres is somewhat longer (28 minutes vs. 25 minutes) and the expense is greater (28 yuan vs. 18 yuan/time), its removal quality is significantly enhanced, and it is better for high-sensitivity discovery, such as qPCR and RNA-seq.
