Area of Science:

  • Biochemistry
  • Immunology
  • Enzymology

Background:

  • Aldolase B is a crucial enzyme in gluconeogenesis.
  • Accurate measurement of aldolase B is important for understanding its role in metabolic disorders and tissue-specific functions.

Purpose of the Study:

  • To establish a highly sensitive and specific enzyme immunoassay for quantifying aldolase B.
  • To determine the distribution and levels of aldolase B in various human tissues and serum.

Main Methods:

  • Development of a sandwich-type enzyme immunoassay using specific antibodies against aldolase B.
  • Purification of antibodies and labeling with beta-D-galactosidase.
  • Measurement of aldolase B in tissue homogenates and serum samples.

Main Results:

  • The assay demonstrated high sensitivity (3 pg/tube) and specificity, with no cross-reactivity to aldolase-A or aldolase-C.
  • Aldolase B was found at high levels in the liver and kidney, and also detected in the small intestine and other examined tissues.
  • Serum levels of aldolase B in healthy individuals ranged from 33 to 202 ng/ml.

Conclusions:

  • A sensitive and specific enzyme immunoassay for aldolase B has been successfully developed.
  • The assay provides a valuable tool for studying aldolase B distribution and levels in various biological samples.
  • Findings contribute to understanding aldolase B's physiological roles and potential involvement in disease states.
