The RNAok™ RNase Inhibitor is a recombinant mammalian RNase inhibitor which possesses very high affinity for eukaryotic pancreatic-type ribonuclease. The RNAok™ RNase Inhibitor forms a 1:1 complex with pancreatic RNase A by noncovalent binding, presenting a noncompetitive inhibitory activity on these pancreatic enzymes. RNAok™ RNase Inhibitor is active against RNase A, RNase B, RNase C but not RNAse H, RNase I, RNase T1, RNase T2, and S1 nuclease. RNAok™ RNase Inhibitor is compatible with RT-PCR enzymes such as AMV, M-MLV and ExcelRT™ Reverse Transcriptase or Taq DNA polymerase.

This product is suitable for extracting total RNA from 50-150mg conventional plantor fungal samples as well as samples rich in polyphenolic and polysaccharides. This kit is based on silica gel column purification technology, and the extraction process does not require the use of toxic phenol chloroform extraction. The entire extraction process only takes 20-30 minutes. This kit adopts DNA filtration technology, which can efficiently filter and remove DNA. The obtained RNA can be directly used for experiments such as RT-PCR, Northern Blot, poly A+ purification, nucleic acid protection, and in vitro translation.

Storage and Stability
Except TCEP, the kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions. After receiving the product, it is recommended to store TCEP (dry powder) at -20-8°C. At low temperatures, Buffer PSL may form precipitates, dissolve it completely by 55°C water bath.
Purchase Guide
1. When dealing with woody or uncommon samples, R4150 is recommended first. R4150 contains two polysaccharide/polyphenol lysis buffer, which is the most universal product.
2. R4151 is recommended for handling common economic crop samples for the first time. Strong lysis solution can be used to process easy-extraction samples. The amount of corn or rice leaves samples can reach up to 300mg.
3. R4165 adopts CTAB/chloroform method, which can also handle a large number of difficult-to-extraction plants, but requires contact with chloroform substitutes, which is less safe than other kits. This kit uses DNase Ⅰ to remove DNA, which is also a good choice for extracting polysaccharide/polyphenol-rich plant samples.
4. R4014 is recommended for fruit/starch plant samples, which uses improved trizol pre-treatment, single column operation and is more economical.

The Fructan Assay Kit is suitable for the specific measurement of fructan in plant extracts, animal feed and food products containing starch, sucrose and other sugars. It is used in three validated methods for the determination of fructan: AOAC method 999.03 (foods), AOAC method 2018.07 (Animal Feed) and AOAC method 2016.14 (infant formula and adult nutritionals).
New, improved procedure.
In the most recent development, a recombinant endo-levanase has been incorporated into the fructanase mixture, extending the use of the method to the measurement of levan-type fructans as are present in grasses such as timothy, cocksfoot, ryegrass and red fescue.
The method described in this booklet employs ultra-pure, recombinant enzymes and specifically measures fructans including inulin-type fructans from chicory, dahlia, jerusalem artichoke; highly branched fructans from onion and wheat stems and leaves; and levan-type fructans from pasture grasses such as timothy grass. The enzymes employed are completely devoid of contaminating enzymes active on β-glucan or gluco-oligosaccharides.
