HowdoIdecontaminatemytissueculture？(Invitrogen)
When an irreplaceable culture becomes contaminated, researchers may attempt to eliminate or control the contamination. First, determine if the contamination is bacteria, fungus, mycoplasma, or yeast. Isolate the contaminated culture from other cell lines. Clean incubators and laminar flow hoods with a laboratory disinfectant, and check HEPA filters. If the cell line or culture is not one-of-a-kind, it is best to thro......阅读全文

MYSPCA3系列
接触角并不复杂，通俗的说，就是液滴在固体表面自然形成的半圆形态相对于固体平面的外切线。接触角的应用非常广泛，甚至可以说涉及到身边的每个细节，比如我们希望汽车玻璃上不沾雨水、但反之我们希望汽车钢板上的油漆永不脱落。其他比如农药和蔬菜叶面、涂料和内外墙面、绝缘油和绝缘材料、纳米材料表面改性等等，从教学科
