96-well Cell Adhesion Assay
(ECM Cell Adhesion Array, Colorimetric Assay)
Catalog Number: ECM-1016 96 assays
Storage: Upon arrival store the components at 4C.
Introduction: Due to its diverse nature and composition, the ECM can serve many functions, such as providing support and anchorage for cells, segregating tissues from one another, and regulating intercellular communication. The ECM regulates a cell"s dynamic behavior. In addition, it sequesters a wide range of cellular growth factors, and acts as a local depot for them. Changes in physiological conditions can trigger protease activities that cause local release of such depots. This allows the rapid and local growth factor-mediated activation of cellular functions, without de novo synthesis.
Formation of the extracellular matrix is essential for processes like growth, wound healing and fibrosis. An understanding of ECM structure and composition also helps in comprehending the complex dynamics of tumor invasion and metastasis in cancer biology as metastasis often involves the destruction of extracellular matrix[3] by enzymes such as serine and Threonine proteases and Matrix metalloproteinase.
BioPioneer Cell Adhesion Microplate Assays are designed for the determination of the relative attachment of adherent cell lines to extracellular matrix proteins such as Human, Human), and Human Collagen IV and Human Laminin.
Principle of the assay
BioPioneer 96-well Cell Adhesion Assays are designed for the determination of cell attachment to ECM proteins. After incubation followed by a brief wash step, attached cells are quantified with the dye. BSA-coated wells serve as a negative control, and poly-L-lysine-coated wells serve as a positive control for general attachment.

最近在做小鼠基因型鉴定，之前做出来的效果很好，没有杂带，只有明显的目的条带，但是最近几次老是出现很多杂带，但是还是看得清目的条带，不影响判断。想请问一下有经验的朋友，这可能是什么原因引起的呢？该怎么避免？谢谢！
TBE作为电泳缓冲液，其中的离子可以导电。并且TE作为DNA的储存液，可以保证DNA免受DNA酶的降解，其中的离子也可以稳定DNA的存在。
biowest agarose 指的是西班牙琼脂糖。
agarose指的是琼脂糖。
手提的斑马鱼RNA再反转录得到CDNA作为模板进行primestar,p的是斑马鱼的全长，但是全长p出来总是带有拖带的情况，有一个情况较好的图是这样的（mark左边的那一条）
我就用这个pcr的产物作为模板又做了一次，结果如下
求大神赐教！！！
请问各位大神，配制琼脂糖胶的电泳浓度是怎么设定，比如百分之1或百分之1.5的浓度是怎么设置，是1.5g的琼脂糖粉加100g的TAE麽？
