Background Information
The human epidermal growth factor receptor (HER) family of receptors plays a central role in the pathogenesis of several human cancers. HER2 (human epidermal growth factor receptor 2), also known as ErbB2 and Neu, is 1 of the 4 membrane receptor tyrosine kinases (RTKs) and when activated affects cell proliferation and survival. HER2 is expressed in many tissues and its major role in these tissues is to facilitate excessive/uncontrolled cell growth and tumorigenesis. Additionally, HER2 mutations have also been reported in common cancers such as pulmonary, colorectal, and breast cancers, indicating a potential for HER2-directed therapies in these cancers.

FAQ
1、我的样本稀释液有限,如何处理稀释倍数较大的样本?
我们建议您对样本进行梯度稀释。例如,人血清样本需要1000000倍稀释时,您可以分3个梯度,每个梯度100倍,进行稀释:
第一步:取2 uL人血清样本,加入198 uL样本稀释液,混匀得到100倍稀释的人血清样本
第二步:取2uL 100倍稀释的人血清样本+ 198 uL样本稀释液进行稀释,混匀得到10000倍稀释的人血清样本
第三步:取2uL 10000倍稀释的人血清样本+ 198 uL样本稀释液进行稀释,混匀得到1000000倍稀释的人血清样本。
如果样本需要进一步稀释,您可以使用更多梯度。除了我们推荐的样本稀释液,不建议您使用其他溶液或者水稀释。如果您的样本稀释液仍然不足,请联系我们的客服为您提供更多样本稀释液。
2、我没有恒温振荡器,这会对实验时间和结果产生影响吗?
如果您没有恒温振荡器,完成这个实验大约需要 2.5 小时。在加入抗体混合物后,我们建议您将板条37℃下静置孵育2小时。在加入 TMB 后,您只需让板条37℃下静置孵育15分钟即可。我们的研发人员通过对比实验已经证明,尽管信号会略有降低,但您仍然可以获得有效的实验数据。
