Immunofluorescence, Immunocytochemistry and Immunohistochemistry – what’s the difference?

August 7th, 2017

The terms immunofluorescence, immunocytochemistry and immunohistochemistry are often used interchangeably. They are however clearly distinct from one another, and it is important that they are used appropriately to avoid confusion. The prefix, “immuno”, refers specifically to the binding of an antibody to an antigen, while the suffix confers different meanings: Immunofluorescence (IF) is a detection…

Passive versus covalent conjugation of antibodies to gold nanoparticles

July 3rd, 2017

Antibodies can be attached to gold nanoparticles by a variety of methods. These include passive adsorption, covalent attachment to surface-functionalized nanoparticles, and attachment to nanoparticles which have been pre-coated with a binding reagent such as streptavidin, biotin or Protein A/G. Passive adsorption Passive adsorption relies primarily on hydrophobic attractions and electrostatic interactions between the antibody…

Enzyme labels for immunodetection

June 23rd, 2017

One of the most popular methods of immunodetection is to pair an enzyme-labeled antibody with an appropriate substrate. Enzymatic conversion of the substrate produces a colored, fluorescent or chemiluminescent readout, which can be used to determine the quantity of antigen present in the test sample. The most commonly used immunodetection enzymes are Horseradish Peroxidase (HRP),…
