Is there a way to remove hemoglobin from pig kidney homogenate without deactivating enzymes?

[Sigma90]

I would like to measure different enzyme activities in centrifuged pig kidney homogenate. I get out of range errors at 450 nm. The samples are still reddish after centrifugation. Is there a way to remove hemoglobin without deactivating / removing enzymes? Thanks!

Do you  want to measure the amount of each via protein quantitation, or do you want to measure the rate at which an enzyme catalyzes a particular reaction (often called its activity)?  You may need to fractionate your sample with standard protein purification techniques.
