ssDNA Quantification Kit

The ssDNA Quantification Kit is developed for single stranded DNA quantification. The kit includes ssDNA Dye, ssDNA Dilution Buffer, and two ssDNA Standards. Simply dilute the ssDNA Dye with the ssDNA Dilution Buffer, add DNA sample (volume from 1-20 μL), then read the concentration using the Qubit® Fluorometer. The assay is accurate for DNA concentrations from 50 pg/µL to 200 ng/µL based on the line corresponding of the data to standards.

Our kit detects ssDNA by using fluorescent dye that enables sensitive single stranded DNA quantification , including ssDNA viruses, synthetic ssDNA, first-strand cDNA synthesis, denatured DNA, and bisulfate-converted DNA etc. ssDNA quantification is essential for the study of the biological process involves ssDNA.

Features

• • • Optimized for use with the Qubit® Fluorometer
    • Uses the Qubit® ssDNA assay setting
    • Linear range: 1-200 ng ssDNA
    • Cost saving by more than 50%

A series of input ssDNA (200, 400, 600, 800, 1000, and 1200 ng) was used.

The performance of the BioDynami ssDNA Quantification Kit is nearly identical to that of Thermo Fisher’s Qubit ssDNA kit (figure below).

Description 

The ExcelRT™ One-Step RT-qPCR kit (TaqMan, no ROX) is designed for reverse transcription and quantitative real-time analysis of a specific target RNA by one-step reaction. The ExcelRT™ One-Step RT-qPCR kit (TaqMan, no ROX), consisting of One-Step RT Enzyme Mix and 2X One-Step Master Mix, is a convenient kit designed for highly efficient cDNA synthesis and highly specific real-time PCR in a single tube. The One-Step RT Enzyme Mix contains a thermostable ExcelRT™ Reverse Transcriptase and a RNAok™ RNase inhibitor. Consequently, One-Step RT Enzyme Mix can reverse transcribe RNA to cDNA at a wide temperature range from 42 to 60°C and active against RNase A, RNase B and RNase C. By containing specialized hot-start Taq DNA polymerase, which greatly reduce primer-dimer formation and can be activated within 2 minutes, the 2X One-Step Master Mix features high specificity and is suitable for fast cycle program.

Features

• Reverse transcription at wide temperature range (42-60°C)
• High specificity 
• Suitable for fast cycle program
• With no ROX reference dye

Storage

Aliquot to avoid multiple freeze-thaw cycles (stable within 30 freeze-thaw cycles)

Protect from light

-20°C for 12 months

Introduction

Blood samples contain rich DNA, including mitochondrial DNA, genomic DNA, circulating DNA (mostly released into blood after tumor cell apoptosis) in white blood cells, as well as parasitic viral or microbial DNA. These DNA are important parameters in clinical testing or diagnosis, which are also valuable materials for medical research. There are three main issues with extracting DNA from blood samples:

1. The sample is highly infectious, posing great harm to operators and the environment.

2. The source of DNA is complex and aportion of the nucleic acid, such as viral DNA or free DNA, may be lost during the operation, leading to downstream detection failure;

3. Blood sample contains a large amount of impurities and inhibitory factors.

Currently there are many methods available for extracting DNA from whole blood samples, such as phenol chloroform extraction, salting out method, etc. However, these methods require pre-treatment of blood sample, which removes red blood cells and isolate white blood cells in the first step. Due to the requirement that it cannot inactivate or kill pathogens during the process of removing red blood cells, the waste liquid (red blood cell lysate) and consumables may be contaminated by pathogens and become infectious, posing a danger to the entire laboratory environment and operators. In addition, during the process of removing red blood cells, useful nucleic acid information such as viruses, microorganisms, or circulating DNA is also lost, leading to experiment or detection failures.

The HiPure Blood DNA Kits series provided by Magen Company uses silica gel column purification technology, which can directly lyse whole blood samples without the need for white blood cell separation. Whole blood samples are directly mixed with lysates and proteases, resulting in the inactivation of pathogens, greatly reducing the infectivity, environmental pollution, and the chance of operators being infected. Due to the direct lysis and digestion of samples, except lymphocyte DNA, other circulating DNA as well as DNA from viruses and microorganisms, can also be recovered.

This product provides fast and easy methods for purification of total DNA for reliable PCR and Southern blotting. Total DNA (e.g., genomic, viral, mitochondrial) can be purified from tissue, whole blood, plasma, serum, buffy coat, bone marrow, other body fluids, lymphocytes, cultured cells.

Specifications

Principle

This product is based on silica column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, Nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Advantages

• High quality DNA – meet a variety of downstream applications, including PCR, qPCR, enzyme digestion, hybridization, etc.
• High throughput – 96 samples can be processed simultaneously

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.
