  • Agent and process for the determination of calcium
    Patent number: 4871678
    Abstract: An agent and process are used for the determination of calcium in liquids. The agent contains essentially orthocresolphthalein complexone, an acid and a zwitterionic buffer and is characterized in that the buffer contains at least one sulphonic acid amine of the general formula ##STR1## wherein R.sub.1 and R.sub.2 are identical or different and denote H or alkyl, hydroxyalkyl or cycloalkyl having in each case up to 8 C atoms andR.sub.3 denotes alkyl or hydroxyalkyl having up to 8 C atoms.

  • Process and reagent for the determination of .alpha.-amylase
    Patent number: 4857640
    Abstract: A process and a reagent for the determination of .alpha.-amylase involve enzymatic splitting of an .alpha.-amylase substrate in the presence of .alpha.-glucosidase and .beta.-glucosidase and measurement of a fission product. As substrate, there is used a 4-nitrophenyl-.beta.,D-maltoheptaoside electronegatively substituted in the phenyl nucleus.

  • Process and reagent for the determination of .alpha.-amylase
    Patent number: 4698300
    Abstract: A process and reagent are described for the determination of .alpha.-amylase by enzymatic splitting of an .alpha.-amylase substrate in the presence of .alpha.-glucosidase and .beta.-glucosidase and measurement of a fission product. The substrate utilized is a 4-nitrophenyl-.beta.,D-maltoheptaoside substituted in the phenyl ring by an electron withdrawing group, preferably a 2-chloro group.

  • Antibodies against creatinekinase-M8 and process for the production thereof
    Patent number: 4237044
    Abstract: Antibodies against the M subunit of CK isoenzymes having a molecular weight between about 130,000 and 210,000, and inhibiting the enzymatic activity of the M subunit, optionally also in the presence of CK substrates, without inactivating the enzymatic activity of the B subunit of any CK-MB which may be present, are described. A process for the production of these antibodies comprises inoculating animals with activated CK-MM and recovering the antibodies in a conventional manner.

  • Process and composition for determining the activity of creatinekinase-MB
    Patent number: 4067775
    Abstract: A process for determination of CK-MB activity in a sample of a body fluid comprising the steps of incubating the sample, optionally in the presence of CK substrates, with antibodies which inhibit enzymatic activity of the M subunit in CK isoenzymes MM and MB without inactivating enzymatic activity of the B subunit in any CK-MB which may be present and determining the activity of the CK B subunit in the resultant sample.
