Template Name Template Description
Affinity (1 ml) — Linear 
Gradient
This method is used to purify many samples quickly. Using a 
sample inlet valve and the sample pump, the method loads 
sample onto separate affinity columns and washes unbound 
material off in quick succession. This process can be repeated 
for up to five columns. This method is designed to reduce the 
target protein’s exposure to proteases. The target proteins are 
then eluted from each column sequentially using a linear 
gradient.
Affinity (1 ml) — Step (Manual 
Load)
This method is used to purify many samples quickly. Using a 
loop valve (a column switching valve plumbed to the injection 
valve in the loop position with multiple sample loops), the 
method loads sample onto separate af
finity columns and 
washes unbound off material in quick succession. This 
process can be repeated for up to five columns. This method 
is designed to reduce the target protein’s exposure to 
proteases. The target proteins are then eluted from each 
column sequentially using a step gradient.
