Immunoprecipitation (IP). Immunoprecipitation (IP) is the small-scale affinity purification of antigens using a specific antibody and is one of the most widely used methods for antigen purification and detection.This approach enables researchers to: 1  identify the activation status of proteins. 2  determine post-translational protein modifications.hromatin immunoprecipitation (ChIP) assays are performed to identify regions of the genome with which DNA-binding proteins, such as transcription factors and histones, associate. In ChIP assays, proteins bound to DNA are temporarily crosslinked and the DNA is sheared prior to cell lysis.

TAVARES, Fla. â The grade-schoolers, lined up in the hallway in their uniforms, look skyward and beam with joy. Tacko!!! they yell. He peers down at them through his glasses, grinning and reaching his long left arm out. To the kids, these are very high-fives: Tacko Fall, high school senior, is 7-feet-6-inches tall. And growing. The morning greeting looks like a homecoming for a visiting hero, even though Fall is simply on his way to the gymnasium during his free period at Liberty Christian Prep.
