What is claimed is:

1. A method for purification of a proteinaceous material from a mixture of the proteinaceous material and interferants comprising:
a) supplying a first end of a hollow fiber filter with a mixture of a proteinaceous material having a molecular weight between approximately 50,000 and 1,000,000 and interferants having a molecular weight that is less than 50% of the molecular weight of the proteinaceous material to a first end of a hollow fiber filter;
b) applying a pressure force to a lumen of the hollow fiber filter to cause the interferants in the mixture to pass through the membrane of the hollow fiber filter;
c) adding buffer or other fluid which does not react with the proteinaceous material to further cause the interferants to pass through the membrane of the hollow fiber filter; and
d) recovering the proteinaceous material from a second end of the hollow fiber filter, said second end being disposed at an opposite end of the hollow fiber filter from the first end.
2. The method of claim 1, wherein said proteinaceous material is selected from the group consisting of antibodies, activated antibodies, fluorescent labels, activated fluorescent labels, and conjugated antibody fluorescent label.
3. The method of claim 1, wherein said interferants have a molecular weight that is less than 10% of the molecular weight of the proteinaceous material.
4. The method of claim 1, wherein said pressure force used to cause the interferants in the mixture to pass through the membrane of the hollow fiber filter is a positive pressure force.
5. The method of claim 1, wherein the hollow fiber filter has a molecular weight cut off of from about 1,000 to 50,000.
6. The method of claim 1, wherein the proteinaceous material recovered from the second end of the hollow fiber filter is at a concentration greater than 40%.
7. The method of claim 1, wherein the proteinaceous material recovered from the second end of the hollow fiber filter is at a concentration greater than 60%.
8. A method for purification of a biological macromolecule from a mixture of the biological macromolecule and interferants comprising:
a) supplying a first end of a hollow fiber filter with a mixture of a biological macromolecule having a molecular weight between approximately 20,000 and 2,000,000 and interferants having a molecular weight that is less than 50% of the molecular weight of the biological macromolecule to a first end of a hollow fiber filter;
b) applying a pressure force to a lumen of the hollow fiber filter to cause the interferants in the mixture to pass through the membrane of the hollow fiber filter;
c) adding buffer or other fluid which does not react with the biological macromolecule to further cause the interferants to pass through the membrane of the hollow fiber filter; and
d) recovering the biological macromolecule from a second end of the hollow fiber filter, said second end being disposed at an opposite end of the hollow fiber filter from the first end.
9. The method of claim 1, wherein said biological macromolecule is selected from the group consisting of nucleic acids and complex carbohydrates.
10. The method of claim 1, wherein said interferants have a molecular weight that is less than 10% of the molecular weight of the biological macromolecule.
11. The method of claim 1, wherein said pressure force used to cause the interferants in the mixture to pass through the membrane of the hollow fiber filter is a positive pressure force.
12. The method of claim 1, wherein the hollow fiber filter has a molecular weight cut off of from about 3,000 to 5,000.
13. The method of claim 1, wherein the biological macromolecule recovered from the second end of the hollow fiber filter is at a concentration greater than 20%.
14. The method of claim 1, wherein the proteinaceous material recovered from the second end of the hollow fiber filter is at a concentration greater than 30%.
