Description

Attogene’s Human IgG/IgM universal lateral flow assay kit is a ready-to-use, universal test strip, which is based on the lateral flow technology that uses gold 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.

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.

Overview

• Reliable and cost-effective
• Non-invasive, user-friendly, convenient sample collection & preservation in a single tube system
• Preserved exosomes are stable for 2 years at ambient temperature
• Shipping accessories can be purchased separately
• Compatible with Norgen’s Saliva Exosome Purification Kit (Cat. 65300)
• RNA can be isolated from the purified exosomes using Norgen’s Exosome RNA Purification kit (Cat. 58000)

Norgen’s Saliva Exosome Collection and Preservation Kit is an all-in-one solution designed for 1) simple and non-invasive saliva collection; 2) preservation of exosomes in saliva samples at ambient temperature; and 3) isolation of high quality intact exosomes and exosomal RNA within a laboratory setting. The Saliva Exosome Collection, Preservation and Isolation Kit contains 50 Individual Saliva Exosome Collection and Preservation Devices. Each of the 50 individual Saliva Exosome Collection and Preservation Devices consists of 3 components:

• Saliva Collection Funnel and Collection Tube that contains Norgen’s Preservative in a dried format
• Collection Tube Cap
• ID Label

Saliva samples are collected by spitting inside the Collection Funnel which has been assembled with the Collection Tube. After collecting the required volume of saliva the Collection Funnel is removed, the Collection Tube is securely capped with Collection Tube Cap. The collected saliva is mixed by gentle inversion for several times till the saliva colour changes into yellow. The Saliva Collection Tube is subsequently sent to the laboratory for the purification of intact exosomes and for the subsequent isolation and analysis of saliva exosomal RNA. The saliva exosomes in preserved samples are stable for 2 years at room temperature.
