Highly Sensitive, rapid, robust screening kit for sample phosphatase activity.

Description

For plate-based colorimetric enzymatic determination of alkaline phosphatase:

Distributed in almost every tissue of the body, serum alkaline phosphatase (ALP) levels are of interest in the testing for hepatobiliary disorder and bone disease. Most of the ALP in the normal adult serum is from the liver or biliary tract. Normal alkaline phosphatase levels are age-dependent and are elevated during periods of active bone growth. Moderate elevations of ALP (not involving the liver or bone) may be attributed to Hodgkin’s disease, congestive heart failure, and abdominal bacterial infections.

Alkaline phosphatase (ALP) catalyzes the hydrolysis of phosphate esters in an alkaline environment, resulting in the formation of an organic radical and inorganic phosphate. In mammals, this enzyme is found mainly in the liver and bones. Marked increase in serum ALP levels, a disease known as hyperalkalinephosphatasemia, has been associated with malignant biliary obstruction, primary biliary cirrhosis, primary sclerosing cholangitis, hepatic lymphoma, and sarcoidosis.

The kit contains sufficient materials to rapidly test 42 samples in duplicate.

Highly Sensitive, rapid, robust screening kit for sample phosphatase activity.

Introduction

Free-circulating nucleic acids, such as tumor-specific extracellular nucleic acid fragments and mRNAs in the blood or fetal nucleic acids in maternal blood, are present in serum or plasma usually as short fragments, <1000bp(Nucleic Acid). The HiPure Circulating Nucleic acid Micro Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. Samples can be either fresh or frozen (provided that they have not been frozen and thawed more than once). Free-circulating cell-free DNA, RNA or viral nucleic acids are eluted in Nuclease Free Water, ready for use in amplification reactions or storage at -30 to -15°C. Purified nucleic acids are free of proteins, nucleases, and other impurities.

Principle

This product is based onsilica column purification. The sample is lysed and digested with lysate andprotease, DNA is released into the lysate. Transfer to an adsorption plate andfilter column. Nucleic acid is adsorbed on the membrane, while protein is notadsorbed and is removed with filtration. After washing proteins and otherimpurities, Nucleic acid was finally eluted with low-salt buffer.

Advantages

• High yield – most optimal process, free DNA (>50bp) can be obtained to the maximum extent
• High concentration – low elution volume, ensuring high nucleic acid concentration
• High purity – low alcohol binding method, completely removing inhibitor and protein pollution
• High recovery – DNA can be recoveredat the level of PG by silica gel column purification

Storage and Stability

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