title: Plant asparaginase-based asparagine biosensor for leukemia.
abstract: The present work aims at the development of plant asparaginase-based asparagine biosensor for leukemia. It is a novel diagnostic for monitoring asparagine levels in patients suffering from acute lymphoblastic leukemia (ALL). Various immobilization strategies have been applied to improve the stability of the asparaginase. The latest and updated information including some new techniques of immobilization related to L-asparaginase such as gelatin, agarose, agar, and calcium alginate methods are described in detail along with response time studies and comparative data. Furthermore these immobilization techniques have been applied for the detection of asparagine in normal and leukemia serum samples.
