    Abstract: A medium for storage and subsequent analysis of a genetic material includes a support for immobilizing the genetic material thereon and allowing subsequent elution of the genetic material therefrom and a coating functionally associated with the support for enabling cellular lysis and releasing the genetic material from the lysed cells while stabilizing the immobilized released genetic material. A method of storing the genetic material and subsequently analyzing the genetic material includes the steps of immobilizing the genetic material on a support while enabling cellular lysis and release of genetic material from the lysed cells and stabilizing the immobilized released genetic material on the support. The genetic material is then eluted to generate a soluble genetic material fraction. The eluted genetic material can be analyzed.

    Abstract: A process for the selective dialysis of liquid streams containing different materials comprises the steps of providing a porous membrane in a cell, the membrane having pores of sufficient dimension to allow passage of the different materials therethrough, circulating an affinity adsorbent stream against a first side of the membrane, where the adsorbent has a dimension larger than that of the pores and has a binding capacity for at least one but not all of the different materials and, passing the liquid stream containing the different materials against a second side of the membrane whereby certain of the materials become bound to the adsorbent upon passing through the membrane to the first side thereof and become separated from others of the materials which can return to the second side of the membrane. A separate stripping process is also provided which can be employed in conjunction with the dialysis process or alone where it is desirable to remove bound materials from an affinity adsorbent material.

    Abstract: A scrubbing process for high feed concentrations of different materials in liquid streams. The process calls for providing a porous membrane in a cell, the membrane having pores of sufficient dimension to allow passage of the different materials therethrough; providing a first stream comprising the different materials in a liquid carrier, providing a second stream comprising an affinity adsorbent in a second liquid carrier, wherein the affinity adsorbent has a dimension larger than that of the pores and has a preferred binding capacity for at least one but not all of the different materials; mixing the first and second streams together to form a composite mixture wherein a portion of the different materials become bound to the affinity adsorbent and a portion of the different materials remain essentially unbound to the affinity adsorbent; and passing the composite mixture against a first side of the membrane while passing a liquid carrier for any of the unbound material against a second side of the membrane to produce a first exit stream containing the affinity adsorbent and a high concentration of at least one of the different materials and a second exit stream containing the liquid carrier and a high concentration of at least one of the other different materials.

    Abstract: A permselective ion-exchange membrane, preferably comprising hollow fiber(s) immersed within a regenerant, is used to selectively neutralize or suppress the conductivity of electrolyte in a stream of eluent also containing chromatographically separated ions. The invention particularly specifies a chromatographic separating column useful with an electrolyte eluent solution to separate ionic species by elution chromatography, wherein the effluent of the separator column is treated by the described membrane to suppress the conductivity of the electrolyte but not that of the separated ions.
