Pyruvate Kinase Activity Assay Kit

http://www.sapphire-usa.com/700760?gclid=CJuHn-23xLMCFQh66wodikYAOA Pyruvate Kinase Activity Assay Kit A fluorescence-based method for detecting PK activity in erythrocyte lysates, plasma, cell culture samples, and tissue homogenates Pyruvate kinase (PK) catalyzes the formation of pyruvate and ATP from phosphoenolpyruvate and ADP. Deficient expression of PK in erythrocytes is one common cause of hemolytic anemia, and because it is expressed in tumor cells, PK has been studied as a potential tumor target. Cayman's Pyruvate Kinase Activity Assay provides a fluorescence-based method for detecting PK activity in erythrocyte lysates, plasma, cell culture samples, and tissue homogenates. In this assay, PK catalyzes the transfer of a phosphate group from PEP to ADP, yielding one molecule of pyruvate and one molecule of ATP. Pyruvate oxidase then catalyzes the conversion of pyruvate to acetyl phosphate, hydrogen peroxide (H2O2), and carbon dioxide. H2O2, in the presence of horser

Colours to see

What colour are your eyes? Is it black, grey, amber, red, hazel, green or blue? Genetics is the major determinant of a person's eye colour. Chromosome 15 present in a cell's nucleus contains two main genes namely OCA2 & HERC2 that determine the amount and quality of melanin pigment in the iris of the eyes. Melanin pigmentation of the front layers of the iris imparts the colour to the centre of the eyes. Iris is the structure that surrounds the pupil of the eyes. More the melanin, darker the colour and vice versa. For instance, black eyes have more melanin. Heterochromia iridis Hetero means different Chromia means pigmentation or colouring Heterochromia iridis is a rare condition characterised by a difference in color between the iris of one eye and the iris of the other eye. Sometimes, the difference in colour is observed between parts of the same eye.

The Power House

A power house is an installation where energy in the form of electrical power is generated for distribution. The cells in our body also have energy producing powerhouses. Each cell contains not just one but many of these powerhouse organelles. The number and size of these organelles varies from cell to cell depending on the cell's functions. For instance, muscle cells need a lot of energy, and have 1000s of them per cell.Whereas each skin cell has just a few 100 of them. These powerhouse organelles go by the name 'mitochondria' Energy is released by the cell's powerhouse-mitochondria in the form of ATP(adenosine triphosphate). This energy (ATP) is extracted through the metabolism of food by a process called cellular respiration. The process of cellular respiration consists of four distinct stages, namely (1)Glycolysis (2)Pyruvate oxidation (3)Citric acid cycle, and (4)Oxidative phosphorylation i.e., the electron transport chain Of these 4 stages, glycoly
