DRY TYPE ANALYSIS ELEMENT FOR ALBUMIN ANALYSIS

摘要

PURPOSE:To reduce errors due to disturbance by protein, by using an analysis element in which a hydrophilic polymer binder layer containing a pH buffer agent and a porous development layer containing an indicator adapted to change in the color being bonded to albumin are laminated sequentially on a light transmitting non-water permeable support. CONSTITUTION:This invention relates to a dry type analysis element for albumin analysis in which at least one layer of hydrophilic polymer binder layers containing a pH buffer agent and a porous development layer containing an indicator adapted to change in the color being bonded to albumin are laminated integral on a light transmitting non-water permeable support sequentially. The porous development layer is preferably a fibrous development layer represented by a weaving development layer and a knitting development layer in that the indicator can be contained and held easily. The indicator preferably employs acid base indicator pigment indicating errors due to protein. The pH buffer agent shall be a low molecular weight of pH buffer agent component or acid that is allowed to maintain the pH value of a reagent development layer in the range of about 2.0-4.0.
