Bind and elute vs flow through mode

WebThe typical scheme in IEX of binding the target, washing the column and eluting the target is called ’bind/elute mode’ and is often applied in intermediate purification steps for … WebOct 1, 2024 · Weak partitioning mode is different from flow-through mode. In comparison to binding under flow-through mode, increased amount of product binds to the resin under weak partitioning mode [7]. Thus, under this mode the binding of impurities that originally bind stronger than the product is further enhanced, which allows more complete removal …
