Gold nanoparticles from Expedeon

August 23rd, 2017

Each antibody is unique and it is important to have a range of options for making nanoparticle conjugates to achieve the best possible performance in diagnostic assays. Antibodies may be attached to coated gold nanoparticles using simple covalent conjugation technologies or with traditional passive techniques.

Simplifying Antibody Conjugation Process

August 23rd, 2017

Antibodies are widely employed in the quantification of antigens in complex biological samples. Using techniques such as Western blotting, ELISA, and immunohistochemistry researchers are able to measure a single antigen, or perhaps a limited number of antigens, in each sample. In the post-genomics era, advances in multiplex immunoassay technologies now allow scores or even hundreds…

Antibody Purification Guide

August 23rd, 2017

Expedeon specializes in easy to use bioconjugation kits which enable the direct labeling of antibodies or proteins with enzymes, fluorescent labels, biotin, streptavidin, gold nanoparticles, latex beads or oligonucleotides. Unfortunately, many antibodies are provided in buffers which contain additives that are incompatible with labeling technologies, making puri cation a key consideration prior to carrying out…

Guide to labeling your primary antibody

August 23rd, 2017

Antibodies are used to detect and quantify antigens in techniques such as flow cytometry, ELISA, western blotting, immunohistochemistry and lateral flow. The antibody that binds to the antigen is called a ‘primary antibody’ and it confers specificity to the assay. Most types of immunoassays also incorporate a ‘label’ whose purpose is to provide measurability. Assays…

Gold nanoparticles: strange properties and applications in the Life Sciences

July 10th, 2013

Webinars

**This webinar was produced by Innova Biosciences which is now fully integrated with their company, Expedeon Ltd., and have taken the Expedeon Ltd name and logo.   Gold nanoparticles exhibit extraordinary properties quite unlike those of the bulk metal. These properties can be exploited in a variety of assay applications,…
