The milligram quantity of this product will vary from lot to lot. The vial content is dependent upon the protein content and enzymatic activity. The minimum protein content will be 70% and the minimum activity will be 2 units per milligram protein. As an example, a batch that reports a protein content of 100% and an activity of 2 units per milligram protein will have a vial content of 2.5 mg for the 5 unit package size. The protein content and activity are reported in the product Certificate of Analysis. Please see the link below to review a sample or lot specific Certificate:

General description
Application
- Pour mesurer l′effet inhibiteur d′hydrolysats de protéines de blanc d′oeuf sur l′activité de l′ECA par chromatographie liquide de haute performance (HPLC).
- Pour mesurer l′inhibition de l′ECA par du péricarpe de litchi et du blanc de poulet cuit sur un substrat d′hippuryl-L-histidyl-L-leucine (HHL) par HPLC en phase inverse (RP-HPLC) et HPLC, respectivement.
- Pour libérer les protéines ancrées dans le GPI in vitro dans quelques lignées cellulaires telles que HeLa et HEK293, et in vivo dans du sperme de souris.

What is the medical significance of Angiotensin Converting Enzyme (ACE), Product A6778?
1 answer-
Angiotensin-converting enzyme (ACE) produces angiotensin II, a substance that affects the cardiovascular system in numerous ways, including narrowing of blood vessels. This narrowing can cause high blood pressure and cause the heart to work harder. ACE inhibitors treat a variety of conditions, such as high blood pressure, scleroderma and migraines. (Mayo Clinic)

Are there any other known inhibitors of rabbit lung Angiotensin Converting Enzyme (ACE), Product A6778?
1 answer-
Idrapril, the prototype of a new class of angiotensin converting enzyme (ACE) inhibitors, competitively inhibits, with nanomolar apparent Ki, the hydrolysis of hippuryl-glycyl-glycine by rabbit lung ACE. Kinetic Ki and kon and koff values were 470 pM, 3.0±1.5×106 M-1sec-1 and 1.4±0.3×10-3 sec-1, respectively. Reference: Biochemical Pharmacology, 45(6), 1358-1362 (1993).
