The Aflatoxin M1 plate kit is a competitive enzyme-labeled immunoassay. The Aflatoxin M1 sample extract and calibrators are pipetted into the test wells followed by the Aflatoxin M1 antibody into the test wells to initiate the reaction. During the 30 minutes incubation period, Aflatoxin M1 from the sample and Aflatoxin M1 antigen compete for binding to the Aflatoxin M1 antibody. The Aflatoxin M1 antibody is captured on the walls of the test well. Following this 30-minute incubation, the contents of the wells are removed and the wells are washed to remove any unbound Aflatoxin M1 and free Aflatoxin M1 antibody. After wash, 1X HRP-conjugated Antibody#2 is added for 30 minutes incubation. The wells are washed afterwards, and a clear substrate is then added to the wells and any bound enzyme conjugate causes the conversion to a blue color. Following a 15-minute incubation, the reaction is stopped and the amount of color in each well is read. The color of the unknown samples is compared to the color of the calibrators and the Aflatoxin M1 concentration of the samples is derived.
Purify sequencing extension products from dye terminators, primers and other contaminants
Also purify DNA from different enzymatic reactions including restriction enzyme digests, Klenow reactions, alkaline phosphatase reactions, and ligations.
High recovery
Fast and efficient spin column format
Also available in 96 well format for high throughput
This kit provides a rapid spin column procedure for the purification and clean-up of sequencing and various other enzymatic reactions including restriction enzyme digests, Klenow reactions, alkaline phosphatase reactions, and ligations. The kit is used to remove reaction contaminants including dye terminators, salts, enzymes, excess primers and primer dimers. Contaminants are undesirable as they can interfere with many downstream applications including sequencing, RFLP, restriction enzyme digestions and ligation. Purification is based on spin-column chromatography without the use of phenol, chloroform or alcohol precipitation. The kit provides a high quality product with up to 90% recovery.
The kit is also available in a 96-well format for high-throughput sequencing reaction clean-up. Purification with the 96-well plate can be performed using either a vacuum manifold or centrifugation.
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.

Product Info
The NGS Cell Free DNA Library Prep Kit (illumina and MGI Platforms) was developed for the construction of high quality cell-free DNA (cfDNA) libraries using 1 ng to 50 ng of cell-free DNA as input. The kit has a simple work flow and a fast procedure. Multiplexing of the cell free DNA library is possible based on the index type.
NGS Cell Free DNA Library Prep Kit Workflow
The main source of cell-free DNA (cfDNA) is derived from apoptotic hematopoietic cells in blood and found in the plasma. The length of the cfDNA is about 150-200 bp in length. Circulating tumor DNA (ctDNA) derived from malignant tumors is a part of cfDNA. Both cfDNA and ctDNA can be used as a noninvasive biomarker since it offers a better approach in comparison to invasive tissue biopsies.
NGS has been used for cfDNA and ctDNA sequencing in the field of liquid biopsy as it provides a whole genome level of molecular profiling. One of the hurdles for cfDNA sequencing is the difficulty of library preparation from the limited amount of cfDNA obtained from plasma. Our cell-free NGS kit makes it easy to get enough libraries from limited input in just 1.5 hours.
Three index types are available for the NGS Cell Free DNA Library Prep Kit of the illumina platform:
Non-index (Cat.# 30029): Libraries do not have index.
Index(Cat.# 30031): Each of our index primers contains a unique 6-base index sequence that can be used for sample identification. Total 48 library multiplexing is possible. Index information can be downloaded here.
Unique dual index (Cat.# 30033): Cell-free DNA library multiplexing up to 96 samples is possible with the unique dual indexes. We have developed a Four-Base Difference Index System. The system have at least 4 bases different from each other in the 8 bases index length. The primers effectively minimize sequencing errors such as mis-assignment, index hopping, index contamination etc. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34031).
Kit advantages:

Blank lateral flow strips are the perfect companion during the development and feasibility testing of a lateral flow device. IN THE BEGINNING, the capture and test line reagents can be spotted onto the nitrocellulose portion of the blank strips at different concentrations, volumes and buffer conditions. This enables the user to determine the optimal conditions for subsequent spraying and enables the user to verify the test and controls will respond according to expectations before scaling up the process.
These blank strips are compatible with all of our colloidal gold products AND:
Lateral flow cassettes: C02022
Streptavidin CdSe/ZnS Quantum Dots For Lateral Flow: AU2043
Streptavidin Europium Chelate Microspheres For Lateral Flow: AU2050
Streptavidin Colloidal Gold For Lateral Flow: AU2017
Twenty 4.5X60mm strips of each combination of nitrocellulose (4X), wicking material (2X), and sample pad (3X)
