This is course 2 of a 6-part xMAP Bead-Based Immunoassays series. This course will give you an understanding of xMAP technology in detail that the Bio-Plex instruments are based on and the Bio-Plex assay format types.  

These series of courses were developed from a collection of frequently asked questions and challenges faced in the field and led by Bio-Rad’s field application scientists and marketing product managers.

These courses are structured to gradually progress from understanding the basics of immunoassays to understanding xMAP technology, running xMAP bead-based assays, and data analysis on the Bio-Plex Manager software. 

They are designed for anyone who is new to Immunoassays and xMAP technology as well as experienced xMAP bead-based assay users who would like to gain a deeper understanding of the technology and assays. Along the way, you’ll learn some tried and tested tips and tricks that will be useful in running successful xMAP bead-based multiplex assays.    

You will receive a downloadable certificate upon successful completion of each course.
