General description
Pyruvate kinase (PK) is an enzyme that catalyzes the final step of glycolysis, the transfer of a phosphate group from phospho(enol)pyruvate (PEP) to ADP, yielding one molecule of pyruvate and one molecule of ATP. Pyruvate kinase deficiency, due to defects in pyruvate kinase expression or activity, is the second most common cause of hemolytic anemia.
The Pyruvate Kinase Activity Assay Kit provides a simple and direct procedure for measuring pyruvate kinase activity in a variety of biological samples. Pyruvate concentration is determined by a coupled enzyme assay, which results in a colorimetric (570 nm)/ fluorometric (λex = 535/λem = 587 nm) product, proportional to the pyruvate present. One unit of pyruvate kinase is the amount of enzyme that will transfer a phosphate group from PEP to ADP to generate 1.0 μmole of pyruvate per minute at 25 °C.

What is the optimal cell quantity for conducting an assay with the Pyruvate Kinase Activity Assay Kit, particularly MAK072, and is this kit appropriate for use with red blood cells?
1 answer-
Optimization for the specific sample type is necessary. Typically, the protocol involves using 1 million cells or 10 mg of tissue suspended in 150-200 microliters of assay buffer.

请问一下这个是否适用于红细胞PKR检测，并且是否要破裂细胞，同时有酶标仪和九六孔板即可完成相关检测。
1 answer-
Theoretically, the Pyruvate Kinase (PK) Assay Kit should work with isolated red blood cells (RBC). However, RBC has not been purified or tested with this kit, therefore, no specific protocol recommendations can be made.
The end-user will have to determine the suitability using a reliable way to isolate RBC. Fresh whole blood coagulates which might negatively influence the isolation of RBC. Hence the isolation of RBC as well as the protocol for the PK Assay kit will have to be optimized for the intended application. This kit is labeled as being able to be used with blood as authors in the following citation used this kit for pyruvate kinase in plasma isolated from whole blood.
