More Details

  • CREATINE is present in vertebrates and helps to supply energy to muscle. In humans and animals, approximately half of creatine originates from food (mainly from fresh meat). Creatine supplementation has been investigated as a possible therapeutic approach for the treatment of muscular, neuromuscular, neurological and neurodegenerative diseases. Simple, direct and automation-ready procedures for measuring creatine are popular in research and drug discovery. BioAssay Systems creatine assay is based on enzymatic reactions leading to formation of a pink colored product. The optical density at 570 nm or fluorescence intensity at λ ex/em = 530/585 nm is directly proportional to the creatine concentration in the sample.

Can this kit be used to measure creatine concentrations in cells?

Yes. To determine intracellular creatine concentrations, harvest cells (0.1-2 million cells per assay) in a 1.5mL tube, centrifuge 1-2 min at 3,000 rpm on a table centrifuge. Remove culture medium, wash cells quickly with cold PBS. Immediately remove any PBS. Prepare Working Reagent. Add 120 µL WR directly to the cell pellet and 80 µL WR to standards in 96-wells. Vortex cell sample tube 1 min, incubate 30 min at room temp. Centrifuge 5 min at 14,000 rpm. Transfer 100 µL supernatant to 96-well. Read OD570nm on a plate reader. Notes: 1. cell number. It is prudent to run several doses of cells, e.g. 0.1, 1, 2×106 cells to determine optimal cell number to be used in subsequent assays. Working Reagent should contain a lysis reagent. BioAssay Systems will supply this reagent upon request.For more detailed product information and questions, please feel free to Contact Us.

BioAssay Systems酸性磷酸酶(ACP)是一种在消化过程中催化磷酸基团从其他分子上裂解的酶。酸性磷酸酶可以在溶酶体中发现,并在与内体融合,酸化pH值后变得有活性,从而为ACP创造了最佳环境。ACP还可以在骨骼,脾脏,肝脏,肾脏和血液中发现。血清水平可以用作前列腺癌的生物标志物,尽管前列腺特异性抗原(PSA)被更广泛地使用。BioAssay Systems非放射性比色ACP分析基于从合成底物上裂解对硝基苯酚。加入终止剂后,对硝基苯酚会显色。加入终止剂后在405 nm处吸光度的增加与酶活性成正比。
