Description

Attogene’s Human IgG/IgM universal fluorescent lateral flow assay kit is a ready-to-use, universal test strip, which is based on the lateral flow technology that uses 655nm Emission Quantum Dot particles containing streptavidin to conveniently capture biotinylated antigens. The device is designed to easily develop qualitative or quantitative rapid test systems for detection of anti-human IgG and IgM antibody that react to the any antigen that can be biotinylated (i.e. viral antigen, autoimmune antigen) and is easily customizable providing every laboratory with the possibility to perform assay feasibility.

Formats (fluorescent broad range UV light excitation range of 300nm to 400nm, 610nm emission) Streptavidin conjugate pad):

Antibody tests are a method of choice to determine if a person has been exposed to a pathogen or not. They are also incredibly valuable in the detection of autoantibodies that can be found in human autoimmune disorders. In this test, a biotinylated antigen (User supplied) is mixed with a biotinylated rabbit IgG (bind to goat anti rabbit control line) and sample (human sera or plasma) is simply mixed into with the specially designed assay running buffer in a well of the supplied 96-well plate, mixed and is then added to the sample port of the cassette. Generally, the reaction is complete in 10-15 minutes. It is very important to note that the relative stoichiometry between the biotinylated antigen, biotinylated rabbit IgG added, and the streptavidin gold is critical for assay optimization. The appropriate concentration of biotinylated antigen to use with strips is dependent upon the purity and sequence and a standard curve can be used to determine the relative ratio (generally between 1ng-100ng per test). A positive control line (biotin-rabbit IgG) antibody will bind to the goat anti rabbit (GAR) line on the test to ensure the assay is running appropriately.

DBCO-PEG5-TFP Ester is an amine-reactive, labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers. The hydrophilic polyethylene glycol (PEG) spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules.

Introduction

Free-circulating nucleic acids, such as tumor-specific extracellular DNA fragments and mRNAs in the blood or fetal nucleic acids in maternal blood, are present in serum or plasma usually as short fragments, <1000bp (DNA). HiPure Circulating DNA Midi Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. The extracted products can be used for clinical in vitro detection.

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.

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 recovered at thelevel of PG by silica gel column purification

Storage and Stability

Proteinase K, Carrier RNA 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 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 be redissolved before use. Make sure that all buffers are at room temperature when used.
