WebJul 1, 2016 · I will measure fluorescence using clear-bottom 96 well plate. I understand that using plate coated with poly-D-lysine is to enable cell adherence. However, from … WebArguably the simplest affinity tag is the polyhistidine (His) tag. Small and unlikely to affect function, His-tagged proteins can be purified using metal-affinity chromatography, usually using a Ni2+ column. Like other affinity tags, a His tag can be fused to either the N- or C-terminus of a protein. gregg county cad tx
