Description 

AccuBand™ 100 bp DNA marker II is composed of 6 individual DNA fragments, presenting 2k, 1k, 750, 500, 250 and 100 bp sharp bands respectively. This product contains 1 enhanced band (750 bp) for easy identification of bands. AccuBand™ 100 bp DNA marker II is ready-to-use, containing loading buffer with tracking dyes of dual colors (orange and cyan). To improve the faint visibility of low molecular weight bands frequently occurred in use of conventional DNA markers, AccuBand™ 100 bp DNA marker II provides sufficient amount of DNA for 250 and 100 bp fragments, and thus ensuring clear observation of all DNA bands ranging from 100 bp to 2k bp, either in agarose gel or in polyacrylamide gel electrophoresis.

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.

Sample type purification kit guide 

The 16S V2-V3 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V2-V3 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 V2-V3 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 V2-V3 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.
