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.

Overview
Isolate and extract high quality & quantity miRNA in 30 minutes
Two column kit- eliminate large RNA on the first column and capture microRNA on a second column
Elute microRNA in 25 µL ready for miRNA profiling
Process a wide range of samples- cell, tissue, bacteria, bodily fluids, etc.
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
This kit provides a rapid method for the isolation and purification of small RNA molecules (< 200 nt) from cultured animal cells, small tissue samples, bacterial cells, plants, and blood.
Two columns are provided with this kit. The first column captures large RNA, while the small RNA are captured on a second column and are eluted concentrated in 25 µL of nuclease-free water.
The small RNA can be used in various downstream applications relating to miRNA profiling, gene regulation, and functional analysis. The eluted RNA is ready for RT-qPCR, microarrays, and NGS applications.
Background
These small RNAs include regulatory RNA molecules such as microRNA (miRNA) and short interfering RNA (siRNA), as well as tRNA and 5S rRNA. Small RNA molecules are often studied due to their ability to regulate gene expression. miRNAs and siRNAs are typically 20-25 nucleotides long and regulate gene expression by binding to mRNA molecules and affecting their stability or translation.
Maximum Amount of Starting Material: Animal Cells Animal Tissues Bacteria Plant Tissues Blood
3 x 106 cells 5-25 mg 1 x 109 cells 50 mg 100 μL
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 1 year after the date of shipment.
The kit is developed for RNA quantification. The RNA Quantification HS kit includes HS Dye, HS Dilution Buffer, and two RNA Standards. Simply dilute the HS Dye with the HS Dilution Buffer, add RNA sample, then read the concentration using the Qubit Fluorometer. The assay is accurate for RNA concentrations from 250 pg/µL to 100 ng/µL (Figure 1). The RNA Quantification High Sensitivity Kit has several advantages over traditional RNA quantitation such as stability, sensitivity, and contaminant tolerance.
Features
Optimized condition for using with the Qubit Fluorometer
Uses the Qubit RNA High Sensitivity assay setting
Cuts costs by 60%
The performance of the BioDynami RNA Quantification HS kit is nearly identical to that of Thermo Fisher’s Qubit RNA HS kit (figure below).
Common contaminants such as detergents, solvents, salts, free nucleotides, or protein are well tolerated in the assay (Table 1).

The 16S V3-V5 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V3-V4 amplicon libraries to be used for next-generation sequencing on Illumina platforms. All molecular reagents including primers, enzyme mixes, indexes, and buffers are provided. Instructions for PCR clean up with the AMPure XP Magnetic Beads (supplied by customer) are also included for rapid purification of nucleic acid products generated at two steps of the workflow. The library prep workflow could be used for purified DNA inputs from different sources including stool, soil, water, saliva, plant, urine, skin swab, vaginal swab, cheek swab, nasal swab, plasma/serum, tongue swab, gum swab, and others.
The 16S V3-V5 Library Preparation Kit for Illumina has a streamlined procedure that reduces the handling time such that the library prep procedure can be completed in approximately 4 hours (see diagram below). Input DNA is first subjected to targeted PCR to amplify the V3-V4 region of the DNA encoding 16S rRNA. The post-PCR reaction is then cleaned up using AMPure XP beads. Dual index primers are then added using a limited-cycle PCR. The indexed amplicons flanked by 5′ and 3′ barcoded adaptors are then cleaned using AMPure XP beads. The libraries are then ready for quantification, pooling and sequencing.
Storage Conditions and Product Stability Norgen’s 16S V3-V5Library Prep Kit for Illumina is shipped as one kit box (for the 24 prep kit) or two sub-component kits (for the 96 prep kit). All kits should be stored at -20°C upon arrival.
All kit components should remain stable for at least 1 year when stored at the specified storage conditions.
