Abstract
The apparatus of the present invention comprises an integrated membrane for separation and preservation of biomolecules. Biomolecules, such as those in blood, can be separated and preserved. The apparatus includes a housing having a matrix portion, and a fluid collection portion disposed within an inner cavity. The housing further includes an aperture permitting access to the inner cavity. The apparatus also includes a matrix disposed within the matrix portion. The matrix includes a first layer for collecting cells from the fluid, a second layer for protein adsorption, and a third layer for nucleic acid adsorption. Fluid enters the housing through the aperture, passes through the matrix, and into the fluid collection portion. Cells from the fluid in a layer of the matrix are collected; adsorbing protein from the fluid in a layer of the matrix; and adsorbing nucleic acid from the fluid in a layer of the matrix.
