ABSTRACT:
White blood cells (WBC) were recovered from dried blood spots on Guthrie cards by a simple and efficient prototypic method. The mummified formed elements of dried blood on filter paper are first fixed, then the red blood cells laked in-situ. Last, the paper matrix is itself digested away with cellulase in acid buffer, releasing the partially rehydrated, mummified WBC and other cellular materials into suspension for collection and examination.
