Description

Blood Urea Nitrogen Enzymatic Kit is a microplate-based colorimetric
assay for the determination of urea in serum samples produced from blood. Blood urea nitrogen (BUN) is an important marker for normal kidney and liver function. Elevation of BUN levels is often an indication of intestinal and kidney obstruction and cardiac failure. Decreased BUN levels are often associated with kidney and liver damage. BUN is also a very useful tool
for preclinical investigation of experimental drug formulations and BUN levels are commonly used to monitor and attenuate the toxic effects of experimental drug formulations in rodents.

Blood Urea Nitrogen Enzymatic Kit uses an enzyme-based assay to determine urea in liquid samples such as serum. The test is based on a highly proven method for urea determination. The Blood Urea Nitrogen Enzymatic Kit contains sufficient materials to test 42 samples in duplicate. The assay utilizes urease, a metabolic enzyme, to specifically detect urea in serum. The Blood Urea Nitrogen Enzymatic Kit provides rapid, accurate, proven results even in complex liquid mixtures. The limit of detection for the test is 8 ppm urea for serum. The linear range of the assay is 8 – 200 ppm analyte.

Introduction

The Kit is specially designed for simultaneous purification of genomic DNA and total RNA from formalin-fixed, paraffin-embedded (FFPE) tissue sections. The Purified DNA/RNA is used for RT-PCR and PCR detection.

Details

Specifications

Features	Specifications
Main FunctionsC	Co-isolation DNA and RNA from a single FFPE tissue sample
Applications	RT-PCR, cDNA synthesis, PCR and second-generation sequencing, etc.
Purification method	Mini spin column
Purification technology	Silica technology
Process method	Manual (centrifugation or vacuum)
Sample type	FFPE slice, FFPE embedded tissue
Sample amount	No more than six 10µm sections of 150mm2 surface area or three 20µm sections of 150mm2 surface area.

Principle

FFPE samples are incubated in an optimized lysis buffer, which results in the release of RNA and precipitation of DNA. After centrifugation, the RNA-containing supernatant and DNA-containing pellet are then processed separately to purify RNA and DNA. For RNA purification, transfer RNA Lysate to an adsorption column and RNA is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, RNA was finally eluted with low-salt buffer. For DNA purification, transfer DNA Lysate to an adsorption column and DNA is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, DNA was finally eluted with low-salt buffer.

Advantages

1.Use non-toxic dewaxing solution without contact with xylene
2.Obtain both DNA and RNA simultaneously from the same sample. Elute separately without affecting each other (Have the same steps and effects as top brand 80234, perfect substitute.)

Storage and Stability

Proteinase K 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. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
