4.2 Loading start

Push approximately 5 ml of protein
solvent through the unit at any
speed. If you detect air bubbles just
lift plunger a few mm to let it ascend
into the syringe.

4.2 Loading end

The red protein is bound on the
membrane and the contaminant
Amido Black flows through.

4.3 Washing

Wash with 5 –10 ml of equilibration
buffer.

4.4 Elution

Elute with 3 ml elution buffer. 
The unit may not run dry during the
operation. 

The red protein is eluted and concen-
trated at the same time.

4.5 Regeneration

Regenerate the unit by application of
10 ml of equilibration buffer.

4.6 Storage after use

Keep the used unit filled with equili-
bration buffer in presence of an
antimicrobial preservative such as
20 % ethanol.

4.7 Stability

The membranes are stable in a pH
range of 2–12 (long term) and 1–14
(short term). Do not use oxidative
agents, such as hypochlorite or H

4.8 Use of peristaltic pumps or 
liquid chromatography systems

For the operation of Membrane
Adsorber units with a peristaltic
pump or a LC system, specific Luer
Lock adapters are needed (see Order-
ing Information). Proceed as
described under 4.1 Equilibration.
When the unit is filled completely
with equilibration buffer, close the
outlet and remove the syringe. Start
your LC system or peristaltic pump 
at a very low flow rate. When fluid
emerges, stop the pump, connect the
tubing via a Luer Lock adapter to the
inlet of the unit. Make sure that no
air is introduced. Remove the lower
cap. Run the pump until fluid
emerges from the outlet of the unit
and stop it. Then connect outlet of
the unit via Luer Lock adapter to the
LC detector and proceed with load-
ing.

Important note

For in vitro use only. 
Use the units only as described in this
operating instructions.
Follow safety regulations: Wear 
protective gloves, safety glasses and 
a lab coat during work.
