应用

Creatinine Deiminase microbial has been used:

• to immobilize aminosilylated glass beads based biosensor for ammonia/ammonium and creatinine detection in urine
• in creating creatinine-sensing membrane for biophysical studies
• to investigate the bioelectronic tongue for the simultaneous determination of urea, creatinine and alkaline ions in clinical samples

Creatinine deiminase has been used in a study to assess the application of a creatinine-sensitive biosensor for hemodialysis control. Creatinine deiminase has also been used in a study to investigate the bioelectronic tongue for the simultaneous determination of urea, creatinine and alkaline ions in clinical samples.
