The Kit is designed for purification of total RNA, including miRNA and other small RNA molecules (18nt), from cultured cells and various animal and human tissues, including difficult-to-lyse tissues samples. Alternatively, a miRNA-enriched fraction and a total RNA (>200nt) fraction can be purified separately. This Kit combines phenol/guanidine-based lysis of samples and silica membrane–based purification of total RNA. MagZol Reagent, included in the kits, is a monophasic solution of phenol and guanidine thiocyanate, designed to facilitate lysis of tissues, to inhibit RNases, and also to remove most of the cellular DNA and proteins from the lysate by organic extraction.

Main Functions
Isolation miRNA and other small RNA molecules(18nt), from cultured cells and various animal and human tissues, using MagZol reagent and column
Applications
RT-PCR, Northern Blot, poly A+purification, nucleic acid protection and in vitro translation
Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such asguanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein andother impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.
This kit combines acid/guanidine (MagZol) extraction technology with glass fiber filter membrane purification, which can improve the extraction effect of complex samples and samples with low RNA content. After the sample is treated with MagZol reagent and chloroform, the supernatant is added with ethanol to provide appropriate binding conditions, then transferred to the purification column and centrifuged. Macromolecular RNA can be efficiently bound to the membrane. Collect the filtrate containing small RNA, add more ethanol to adjust the binding capacity of small RNA, the pollutants can be efficiently washed away by second cleaning. Finally, the purified RNA was eluted by RNase free water.
Advantages
High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
Fast – several samples can be extracted in 40 minutes
High applicability – samples including animals, plants, bacteria, cells, etc.
High concentration – efficiently remove macromolecular RNA, enrich small RNA and improve sensitivity

Storage and Stability
MagZol Reagent should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect its performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.

T7 RNA Polymerase catalyzes the formation of RNA from a DNA template in the 5’-3’ direction and is commonly used in in vitro transcription (IVT) applications. The enzyme is T7 promoter specific, requires Mg2+ as a cofactor and can use modified nucleotides for the synthesis. The T7 RNA Polymerase requires a double-stranded DNA template and can produce full-length RNA transcripts.
Key Features
T7 promoter-specific RNA polymerase
Available in standard glycerol-based formulation as well as lyophilization-friendly formulation without glycerol.
Suggested Applications
In vitro transcription of RNA
Molecular diagnostics (NASBA and other)

The Digestible and Resistant Starch Assay Kit (K-DSTRS) for the determination of digestible, resistant and total starch in starch samples, plant and other materials.
This method is based on the research of Englyst et al. (Ref) with some modifications. Digestion is performed using saturating levels of pancreatic α-amylase (PAA) and amyloglucosidase (AMG), but in stirred containers rather than shaken tubes, to simplify sample removal.
In line with Englyst definitions:
Rapidly digestible starch (RDS) is that starch which is digested within 20 min.
Slowly digestible starch (SDS) is that starch which is digested between 20 and 120 min.
A new term, ‘Total digestible starch (TDS)’ is introduced (and measured) to cover all starch that is digested within 4 h (the average time of residence of food in the human small intestine).
Resistant starch (RS) then, is that starch which is not digested within 4 h.
The incubation conditions parallel those used in AOAC Method 2017.16, a new, rapid integrated procedure for the measurement of total dietary fiber (Megazyme method K-RINTDF). This method is physiologically based and designed to fit the definition of DF announced by Codex Alimentarius in 2009.
