NobleAgarAssay
DescriptionCancer cells do not show anchorage and contact inhibition of growth. To assess the anchorage and contact independent growth of cells, noble agar assay can be utilized. Noble agar is used to coat the tissue culture plates to cover the polylysine coating of the plate. On this noble agar coated, anchorage independent tissue culture plates normal and cancer cells will be seeded in very low density to prevent t......阅读全文

peg6000－agar为什么会有沉淀
沉淀是肯定的因为PEG本来就与琼脂不相溶，它与黄原胶、海藻酸钠和明胶也不相溶只能与化学结构相似的PVP或者PAM等少数高聚物互溶（PVA都不行），请酌情参考。另外PEG-6000因为分子量高羟值低它溶于热水没问题但是一冷却下来就会析出的，从PEG-2000开始就是分水岭了……
沉淀反应实验：琼脂扩散(agar－diffusion)实验
琼脂扩散实验琼脂扩散是抗原抗体在凝胶中所呈现的一种沉淀反应。抗体在含有电解质的琼脂凝胶中相遇时，便出现可见的白色沉淀线。这种沉淀线是一组抗原抗体的特异性复合物。如果凝胶中有多种不同抗原抗体存在时，便依各自扩散速度的差异，在适当部位形成独立的沉淀线，因此广泛地用于抗原成分的分析。琼脂扩散实验可根据抗原
