RNase activity in a convenient and sensitive colormetric assay that delivers results in real time. Great for Quality Testing for RNase contamination of materials and supplies.
Attogene has developed the first of its kind and patent pending technology that uses a novel RNA substrate tagged on the 5′ and 3′ end with a Biotin that is attached to our streptavidin colloidal gold reporter molecules and a test line tag. In the absence of RNases, the gold tagged RNA molecule will flow up the lateral flow strip and bind to the test line using an anti tag antibody (INDICATING that NO RNase is detected). When RNases are present, however, the RNA substrate is cleaved, and the 5′ and 3′ tags are spatially separated in solution cauing the test line to disapear.
This test can be used to rapidly and efficiently detect ribonucleases in both liquid and on solid surfaces and a perfect tool for monitoring mRNA vaccine manufacturing.

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.

Principle
This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by elution buffer.
Advantages
Economy – less than 50% of the price of Qiagen and other imported products
Automatic – without labour
High purity – OD 260 / 280 : 1.7-1.9, OD 260 / 230 :1.5-2.0

Storage and Stability
Proteinase K, Carrier RNA and MagPure Particles F should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance.Theremaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions.The entire kit can be stored at 2–8°C, but in this case buffers should beredissolved before use. Make sure that all buffers are at room temperature when used.
