|h Fibronectin is a protein purified by affinity chromatography from human plasma. It is pure by SDS-PAGE and is immunoreactive in microplate based ELISAs and in Western Blots. The material is suitable for use as a primary standard in immunoassay methods.
h Fibronectin is supplied in liquid form in urea buffer. The concentration varies with manufacturing lot, but the protein may be used directly in most immunoassays by dilution in appropriate buffers.
Short term storage should be done at 4oC. Long term storage should be completed at -60oC. Repeated cycles of freezing and thawing should be avoided.
