Easy-to-use EPO Purification kits from MAIIA Diagnostics offer a unique system for rapid immuno-affinity purification and concentration of erythropoietins (EPO) from aqueous media such as urine, serum, plasma or cellculture medium.
The anti-EPO column in the kits is immobilized with anti-EPO antibody which captures both endogenous erythropoietin (hEPO) and recombinant erythropoietin (rhEPO) such as Epoetins, NESP, CERA and EPO-Fc. The kits are intended to be used as a preanalytical sample preparation step for further analysis with techniques such as isoelectric focusing (IEF), SARCOSYL polyacrylamide gel electrophoresis (SAR-PAGE) and Membrane Assisted Isoform ImmunoAssay (MAIIA). Several purifications can simultaneously be handled if using appropriate laboratory equipment.

|For larger sample volumes or high EPO concentrations such as cellculture medium. Bindingcapacity 100 – 400 µg EPO / 2 mL gel depending on EPO variant.|
|Purification||Sample passes through a membrane with immobilized anti-EPO antibodies by pressure format. Flow rate 1mL / min. The bound EPO in the membrane is then released with elution buffer and spin off by using a micro centrifuge.||Sample incubates with anti-EPO resin by end over end incubation for 60 – 90 min. Aqueous media is then removed by pressure format. The bound EPO in the resin is then released with elution buffer and spin off by using a micro centrifuge.||Sample passes through a traditional regenerable anti-EPO gel column by gravity format. Flow rate 0,5 – 3mL / min. The bound EPO is then released with elution buffer in the same way.|
