10nm Colloidal Gold for Lateral Flow is a highly stable and uniform 10 nm gold nanoparticles can be supplied in a range from 1 OD to 100 OD. The quality and performance of a conjugate is critical to successful lateral flow test manufacturing. Our products are made in Austin TX and produced in a state-of-the-art manufacturing facility that enable rapid turnaround times while ensuring batch to batch consistency and reliability.
Bulk pricing and manufacturing supply contracts available.
CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
Ideal for use in in vitro diagnostic workflows
Simultaneous isolation of both host DNA and microbial DNA (universal protocol)
Eliminates PCR inhibitors including humic acids
Fully compatible with Norgen’s Stool Nucleic Acid Collection and Transport Tubes
High quality DNA for sensitive downstream applications including PCR, qPCR, sequencing and microarray
This kit provides a convenient and rapid method to isolate total DNA from fresh, frozen and preserved stool samples, including those preserved using Norgen’s Stool Nucleic Acid Collection and Preservation Devices Dx (Cat. Dx45660). The universal protocol conveniently allows for the isolation of total genomic DNA from all the various microorganisms and host cells found in the stool sample simultaneously. The kit removes all traces of humic acids and other inhibitors using Bead Tubes and a combination of chemical and physical homogenization and lysis, without the need of any phenol-chloroform extractions. A simple and rapid spin column procedure is then used to further purify the DNA with high yields and molecular weights of up to 50 kb plus. The purified DNA is of the highest quality and is fully compatible with all downstream applications such as PCR, qPCR, NGS and microarrays since all humic acid substances and other PCR inhibitors are removed during the isolation process.
