FAQ

DomandaRisposta
What is the shelf life of the Prosep A and Prosep G spin columns?The spin columns/media are under warranty for 2 years provided they are stored at 2-8 C.
Do I need to filter the buffers provided with the Montage Antibody Purification kit?The buffers supplied with the kit are pre-filtered for immediate use.
Do I need to pre-filter my sample before loading it onto a Prosep A or ProSep G spin column?All samples must be filtered through a 0.22 mm filter immediately before loading the sample onto the column. We recommend using a Steriflip-GP 0.22 mm filter.
What is the binding capacity of the Prosep A spin column?Using the Prosep A spin columns we have been able to bind >20 mg of Rabbit IgG.
What is the maximum volume I can load onto the Prosep A and Prosep G spin columns?You can load up to 20 ml in a Prosep A or Prosep G sping column for a swinging bucket rotor and up to 10 ml for a fixed angle rotor. We recommend that you spin it in a swinging bucket rotor.
Why do you suggest that the Prosep A spin columns be spun at 100-150 xg for 20 minutes?The low speed, twenty minute centrifugation maximizes IgG / resin contact which increases IgG binding efficiency.
Can I use a fixed angle rotor or a swinging bucket rotor with the Prosep A and Prosep G spin columns?Swing bucket rotors are recommended because they provide uniform flow through the resin. For optimal performance with a fixed angle rotor, ensure that the orientation of the Prosep A spin coulmn is the same for all steps. Also please note that the maximum sample loading volume for a fixed angle rotor is ten ml versus twenty ml with a swinging bucket rotor.
What is the minimum elution volume for the Prosep A and Prosep G spin columns?We suggest 10 ml. Smaller volumes can be used but they may result in incomplete IgG recovery. If you use a smaller volume the neutralization buffer volume should also be adjusted accordingly.
How do I regenerate the Prosep A spin columns?We recommend that you wash the plugs with 10 ml of Elution Buffer B2 by centrifuging at 500 xg got 5 minutes. re-equilibrate the media with 5 ml of Binding Buffer A by centrifuging the spin column at 500 xg for 2 minutes. Proceed to step 1 of the antibody purification protocol for immediate re-use or store the plugs without their end caps in 5 ml of Binding Buffer a in a 15 ml screw-capped tube for future use.
Can I autoclave the Prosep A and Prosep G spin columns?The Prosep A and Prosep G spin columns cannot be autoclaved.
