Vector Laboratories is closed for the President’s Day on Monday, February 19th. We will be back in the office on Tuesday, February 20th.
We will respond to emails upon our return. Have a wonderful day.

Amplified Fluorescent Staining Systems

The VectaFluor™ Excel Amplified Fluorescent Staining System offers a convenient, non-biotin amplification method for immunofluorescence applications. Use the VectaFluor™ Excel kits to:

  • Increase sensitivity by as much as three- to four-fold over that of a fluorophore-conjugated secondary antibody
  • Enable unambiguous visualization of weakly expressed antigens
  • Minimize dilution of potentially expensive primary antibodies 


This fluorescent staining system combines the following to amplify the fluorescence signal:

  • Amplifier Antibody – a proprietary, high-affinity and cross-adsorbed Anti-Mouse IgG or Anti-Rabbit IgG antibody produced in goat
  • VectaFluor™ DyLight® dye-conjugated Anti-Goat IgG antibody optimized for tight binding to the Amplifier Antibody
  • Normal Horse Serum for blocking 


The VectaFluor™ DyLight® dye-conjugated Horse Anti-Goat IgG is conjugated in a manner that ensures the maximum degree of labeling without compromising antibody affinity or specificity. DyLight® dyes offer advantages such as bright fluorescence staining, excellent photostability, and pH independence.

Producing immunofluorescence (IF) staining results with high specificity and sensitivity begins with choosing the best reagents. This guide will help you:

  • Learn about the IF workflow and how to optimize each step
  • Quickly identify and choose the most appropriate fluorescent secondary conjugates
  • Select the best anti-fade medium to preserve your fluorescence signal for imaging and archiving
