Human Adenosine Deaminase
Human erythrocyte adenosine deaminase has been purified approximately 800,000-fold to apparent homogeneity using antibody affinity chromatography. The enzyme was shown to be a single polypeptide chain with an estimated molecular weight of approximately 38,000. The three electrophoretic forms of erythrocyte adenosine deaminase purified simultaneoudy by this technique were indistinguishable by so...
متن کاملHuman Adenosine Deaminase Binding Protein
In many human tissues adenosine deaminase exists as a complex composed of two proteins; one protein has adenosine deaminase activity while the other represents a binding protein with no other known binding activity. A rapid, quantitative assay for human adenosine deaminase binding protein has been developed utilizing ‘251-labeled calf adenosine deaminase. In addition this binding protein has be...
متن کاملHuman adenosine deaminase expression in mice.
A replication defective retroviral vector containing a human adenosine deaminase (hADA) cDNA was produced by GP + E-86 packaging cells at high titer. We report long-term expression of hADA in the hematopoietic tissues of mice transplanted with bone marrow cells infected by in vitro co-cultivation with vector producing cells. Western analysis using an hADA-specific antibody allowed detection of ...
متن کاملADENOSINE DEAMINASE ACTIVITY IN ESTROGEN RECEPTOR POSITIVE AND NEGATIVE HUMAN BREAST CANCER CELL LINES
ABSTRACT Background: The aims of this study were to assay the activity of adenosine deaminase (ADA) in estrogen receptor positive (MCF-7) and negative (MDA-MB468) breast cancer cell lines. Methods: MDA-MB468 and MCF-7 breast cancer cell lines were cultured in complete medium, striped serum with and without 0.0 1~-LM diethylstilbestrol (DES), complete medium in the presence and absence of 111M ...
متن کاملHuman adenosine deaminase. Stoichiometry of the adenosine deaminase-binding protein complex.
In many human tissues adenosine deaminase exists as a large molecular weight complex (large form) composed of adenosine deaminase and an adenosine deaminase binding protein. The molar ratio of adenosine deaminase to binding protein in this large form complex appears to be 2:1, respectively, based on several observations. Scatchard-type analysis of the binding of 125I-labeled adenosine deaminase...
