Abstract
A method of detecting biological substances having affinity properties by passing the substance to be detected in a flow over a solid surface to which surface a second substance, to which the substance to be detected shows affinity, is attached, so that the two substances form a complex and give enrichment of the substance to be detected. The enrichment is obtained when the fluid volume passing the active surface is many times larger than the volume in contact with the active surface. A means for detecting biological substances consisting of a flow of a fluid sample of the substance to be detected generated via a pump over a solid surface to which another substance, to which the first substance to be detected shows affinity, is attached, so that a complex is formed of the two substances and gives enrichment of the substance to be detected.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
