Novel method
PullG6 assay for the measurement of pullulanase employs a water soluble defined substrate, namely 4,6-O-benzylidene-4-nitrophenyl-63-α-D-maltotriosyl-maltotriose (BPNPG3G3), coupled with the ancillary enzymes α-glucosidase and β-glucosidase. Upon hydrolysis of the substrate at the 1,6-α-linkage by pullulanase or limit-dextrinase, the released 4-nitrophenyl-β-maltotrioside is immediately hydrolysed to glucose and 4-nitrophenol by the concerted action of the α-glucosidase and β-glucosidase enzymes in the reagent mixture. The reaction is terminated and phenolate ions are developed by addition of dilute alkali. The absorbance is read at 400 nm and the value obtained correlates directly with pullulanase activity.

Introduction
The HiPure Plant RNA Midi Kit provides fast purification of high-quality RNA from plants, cell, tissues, and yeast using silica-membrane spin columns with a binding capacity of 1mg RNA. There is no need for phenol / chloroform extractions and time-consuming steps such as CsCl gradient ultracentrifugation or precipitation with isopropanol or LiCl. RNA purified using the RaPure Total RNA Purification System can be used for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

Principle
The Kit isolates total RNA from up to 1g plant tissue. A short workflow enables RNA isolation with genomic DNA removal in less than 40 min. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column, ethanol is added to the flow-through, and the sample is applied to a RNA column. RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 400µl water using the Kit.
Advantages
Efficient removal of DNA – unique genomic DNA removal column without DNase treatment
High quality – high purity total RNA can be directly used in various sensitive downstream applications
Fast – medium isolation of several samples can be completed in 40 minutes
Safe – no phenol chloroform extraction required
Sensitive – RNA can be recovered at the level of PG
Broad spectrum – various types of plant samples can be processed by diversity of operating procedures

Storage and Stability
The Kit can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. Make sure that all buffers are at room temperature when used. During shipment, crystals or precipitation may form in the Buffer RLC/PRC1. Dissolve by warming buffer to 37°C.
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.

Norgen’s Plasma/Serum RNA/DNA Purification Mini Kit provides a fast, reliable, reproducible and simple procedure for the sequential isolation of circulating RNA, exosomal RNA and Cell-Free Circulating DNA (cfc) from the same Plasma/Serum sample. It can sequentially isolated RNA and DNA from small plasma/serum input ranging from 10 µL to 200 µL. The kit is designed to isolate all sizes of circulating RNA, including microRNA, all sizes of exosomal RNA as well as all sizes of cfc-DNA from fresh or frozen plasma or serum samples. Norgen’s Plasma/Serum RNA Purification Kit provides a clear advantage over other available kits in that it does not require Phenol/Chloroform or any Protease treatments for the isolation of plasma/serum RNA or DNA . RNA and DNA can be eluted into a flexible elution volume ranging from 10 µL to 25 µL. Purified RNA can be used in a number of sensitive downstream applications including reverse transcription qPCR, reverse transcription PCR, NGS, Northern blotting, RNase protection and primer extension, and expression array assays. Purified DNA can be used in a number of sensitive downstream applications including PCR, qPCR, methylation-sensitive PCR and Southern Blot analysis.
Background
Typical yields of free-circulating, exosomal RNA and cfc-DNA vary depending on the input sample, as the amount of RNA and/or DNA present in plasma and serum will depend upon the health status of the individual. Normally, the RNA/DNA yield from plasma or serum is highly variable (range from 1 to 100 ng/mL). Variability is also observed between samples collected from the same donor at different times during the day. This kit is suitable for the isolation of RNA/DNA from serum or plasma prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications such as RT-PCR.
Note: Do not exceed the recommended sample input volume of 200 µL.
Storage Conditions and Product Stability
All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Influenza virus infection of birds, humans and other animals is a major public health problem worldwide. Influenza viruses are classified as either type A, B or C based on differences in their nucleoproteins and matrix proteins. The type A viruses are the most virulent human pathogens among the three influenza types and cause the most severe disease and epidemics. The different types can be further classified into subtypes based on antigenic differences in two surface glycoproteins; hemagglutinin and neuroamidase. All known subtypes of influenza A can be found in birds (H1-H16, N1-N9), while a limited number of the subtypes have been found in humans (H1-H3, N1 and N2). However, over the past few years, various subtypes of Influenza A viruses, including H5N1, have been reported to infect humans (WHO, 2006). In addition, the coexistence of human influenza viruses and avian influenza viruses may provide an opportunity for genetic material to be exchanged between these viruses. This could potentially create a new virulent influenza strain that is easily transmissible and lethal to humans (Food Safety Research Information Office, 2006). Thus, there is the need for sensitive diagnostic tests to allow for the rapid and early detection of these H5 influenza virus infections, to help reduce the risk of epidemics or pandemics in both animals and humans.
