Description

Protein A Colloidal Gold for Lateral Flow (1mL)

Product image shows functional testing of Protein A 40nm colloidal gold on a lateral flow test. Protein A 40nm colloidal gold was incubated in lateral flow running buffer alone or in the presence of a limiting amount of monoclonal antibody that targets the chemical-BSA conjugate. The gold was then applied to the sample port of a cassette containing a lateral flow strip sprayed with a chemical conjugate (Chemical-BSA) on the test line and a goat anti mouse antibody as the control line. The data demonstrates the specificity and robustness of the Protein A 40nm colloidal gold.

Our products are produced in a state-of-the-art manufacturing facility that enable rapid turnaround times while ensuring batch to batch consistency and reliability.

Functionally tested Protein A conjugated gold
Perfect for Lateral Flow Development and use in final product
40nm gold particles conjugated to Protein A are offered in 10 OD 1mL size. If a different OD or amount is required please

Introduction

Hipure Stool RNA Kit is specially designed for stool RNA extraction. This kit is suitable for extracting high-purity microbial or host cell RNA from ≤0.1g stool samples. The kit adopts silica gel column purification technology and original solution system, which can effectively remove humic acid and other inhibitory factors in stool samples. The purified RNA can be directly used in RT-PCR, Northern hybridization and other experiments.

Principle

The HiPure silica gel column uses a high binding ability glass fiber filter membrane as the substrate. Under the condition of high concentration of ionizing agent (such as Guanidinium chloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bonding and electrostatic and other physical factors, while protein or other impurities are not adsorbed and removed. The filter membrane that has adsorbed nucleic acids is washed to remove proteins and salts. Finally, low salt buffer solution (such as Buffer TE) or water can be used to wash out the nucleic acids adsorbed on the filter membrane. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

The stool samples are homogenized in the lysis solution, further lysed in a high-temperature water bath, and RNA is released into the lysis solution. Chloroform extraction removes genomic DNA and impurities, transfer the supernatant to an alcohol free binding solution, purify RNA through a column, and finally elute RNA with RNase Free Water. The purified RNA can be directly used for experiments such as PCR, Southern hybridization, and enzyme digestion.

Advantages

• High purity – unique adsorbent for more efficient removal of inhibitors
• High concentration – maximum extraction of total RNA from stool samples
• Sensitive – RNA can be purified at the level of PG

Mal-amido-PEG5-alkyne is a PEG linker containing a maleimide group and an alkyne. The hydrophilic PEG spacer increases solubility in aqueous media. The alkyne group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose.
