Long noncoding RNA (lncRNA) was initially regarded as "noise" of genome transcription and had no biological function. After the first eukaryotic lncRNA, H19, was discovered in mice in 1984, more and more studies have shown that it plays an important role in various life activities and has received widespread attention. Compared with mammalian lncRNA, plant lncRNA research is relatively backward, but it can reveal new mechanisms of plant growth and differentiation, and act as a regulatory factor

Qihengxing StarLighter HS Probe qPCR Mix (Universal) is a ready-to-use high-sensitivity probe-based qPCR Mix developed based on hot-start genetically engineered Taq Pro DNA polymerase. Its optimized buffer system can reduce nonspecific amplification and improve amplification efficiency. It is suitable for ultra-high-sensitivity qPCR detection and has been verified by animal single-cell embryo sex detection. It can efficiently amplify template DNA as low as fg level. The polymerase of this produc

Qihengxing StarLighter high-sensitivity probe method qPCR Mix (Cat. No.: FS-Q3002) provides a solution for host DNA residue detection. During the production process of biological products such as recombinant protein drugs, antibody drugs, vaccines and cell therapy products, residual host DNA in the cell culture stage may bring infection risks, carcinogenicity, immunogenicity and other toxicities, and regulatory agencies have established strict standards. Among the exogenous DNA residue detection

The Qihengxing Blood Genome Extraction Kit uses nanomagnetic beads and a special buffer system to purify high-quality genomic DNA from fresh or frozen blood samples. The process is safe and convenient, with high yield and purity and stable quality. The kit is suitable for 0.1mL-1mL whole blood samples, and is suitable for both manual and automated extraction. The extracted products are suitable for PCR, second-generation sequencing, etc. Product advantages include simple process without centrifu

StarPure Gel Purification Kit is a gel recovery kit based on the magnetic bead method. It uses nano-scale silicon hydroxy magnetic beads and a unique gel melting buffer to recover 70bp - 20kb DNA fragments from TAE or TBE agarose gels while removing impurities. It is easy to operate and does not require centrifugation. Gel recovery and purification can be completed in 10 minutes, with a recovery rate of over 90%. It also supports high-throughput and automated operations.

Although the principle of multiplex PCR technology is the same as that of conventional PCR, it is easy to encounter problems during operation and needs to be optimized to obtain better amplification effects. Primer design must meet general principles. It should also be noted that the primers cannot be complementary, especially the 3' end, to avoid the formation of dimers. The complementarity with other amplified fragments and templates should be small, the homology between amplified fragments sh

Multiplex PCR (MPCR) is developed on the basis of conventional PCR. It can add multiple pairs of primers to the same reaction system to amplify multiple nucleic acid fragments at the same time. It is specific, sensitive, faster and more economical, and widely used in many fields. In actual operation, it is necessary to achieve a balance between the amplification conditions of multiple targets to achieve perfect compatibility between primers. Qihengxing StarLighter Multiplex PCR Mix is specially
