Fluorescence conjugated alexa fluor secondary antibodies

Manufactured by Thermo Fisher Scientific
Sourced in United States

Fluorescence-conjugated (Alexa Fluor) secondary antibodies are a type of laboratory reagent used in various immunoassay techniques. These antibodies are designed to bind to and detect primary antibodies, allowing for the visualization and quantification of target molecules in samples. The fluorescent dyes (Alexa Fluor) attached to the secondary antibodies emit light when excited, enabling the detection and analysis of the labeled target molecules.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
