生物活性
|
产品描述 |
Vitamin K2 (Menaquinone)是一种十分重要的脂溶性维生素，在保护心脏和大脑、构建强壮的骨骼过程中发挥重要作用。 |
|
|
靶点 |
Human Endogenous Metabolite |
Human Endogenous Metabolite |
|
体外研究 |
Menaquinone-4 (MK-4, 0, 1, 5, 10μM) increases the ALP activity in Caco-2 cells. Menaquinone-4 (1μM) significantly increases intensities of hSI expression |
|
|
体内研究 |
Menaquinone-4 (K2, 0.2 g/kg diet) in HF-K2 group produces epididymal fat in C57BL/6J mice, and also increases the bone density of mice |
|
推荐实验方法(仅供参考)
|
Cell Assay |
Caco-2 cells are plated at a density of 2-5 × 104 cells/cm2 onto a 35-mm dish. Cells are incubated for 2 to 3 days until 60%- 70% confluency, and desired concentrations of Menaquinone-4 (0, 1.0, 5.0, and 10.0μM) are added. The final concentration of the vehicle is 0.1% of the culture medium, and the culture medium is changed twice a week. Cells are assayed on days 0, 3, 7, and 11 after the addition of Menaquinone-4 |

Animal Administration |
Forty-two male, 4-week-old C57BL/6J mice provided with feed and drink ad libitum. For environmental adaptation, the animals had 1 week of circulation, and then are provided with the experimental diet after being randomly divided into 6 groups (7 animals in each group; randomized block design). The AIN-93G diets consist of a normal diet (N), normal diet + vitamin K1 (N-K1), normal diet + vitamin Menaquinone-4 (N-K2), 45% high-fat diet (HF), 45% high-fat diet + vitamin K1 (HFK1), and a 45% high-fat diet + vitamin Menaquinone-4 (HF-K2). The vitamin K1 and vitamin Menaquinone-4 contents are 200mg/1,000 g, and the diet is provided in pellet form. Body weight is measured once a week, and the food efficiency ratio (FER) is calculated by dividing the increased body weight from day 1 to the final day by the food intake amount during the experiment period. For fat amount measurement, the epididymal fat, perirenal fat, and retroperitoneal fat are extracted from dead animal subjects, are washed with 0.9% NaCl, dried by filter paper, and then are weighed |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系，公式为：
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
