Specificity of the CLIA Kit for Brain Derived Neurotrophic Factor (BDNF)
This assay has high sensitivity and excellent specificity for detection of Brain Derived Neurotrophic Factor (BDNF).No significant cross-reactivity or interference between Brain Derived Neurotrophic Factor (BDNF) and analogues was observed.
Recovery of the CLIA Kit for Brain Derived Neurotrophic Factor (BDNF)
Matrices listed below were spiked with certain level of recombinant Brain Derived Neurotrophic Factor (BDNF) and the recovery rates were calculated by comparing the measured value to the expected amount of Brain Derived Neurotrophic Factor (BDNF) in samples.
| Matrix | Recovery range (%) | Average(%) |
| serum(n=5) | 81-91 | 87 |
| EDTA plasma(n=5) | 85-101 | 90 |
| heparin plasma(n=5) | 92-101 | 96 |
Precision of the CLIA Kit for Brain Derived Neurotrophic Factor (BDNF)
Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Brain Derived Neurotrophic Factor (BDNF) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Brain Derived Neurotrophic Factor (BDNF) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 Intra-Assay: CV<10%>Inter-Assay: CV<12%>
Linearity of the CLIA Kit for Brain Derived Neurotrophic Factor (BDNF)
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Brain Derived Neurotrophic Factor (BDNF) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
| Sample | 1:2 | 1:4 | 1:8 | 1:16 |
| serum(n=5) | 94-102% | 99-105% | 93-105% | 91-103% |
| EDTA plasma(n=5) | 89-97% | 83-95% | 93-105% | 80-97% |
| heparin plasma(n=5) | 91-104% | 86-94% | 79-104% | 98-105% |
Stability of the CLIA Kit for Brain Derived Neurotrophic Factor (BDNF)
The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Test principle of the CLIA Kit for Brain Derived Neurotrophic Factor (BDNF)
The microplate provided in this kit has been pre-coated with an antibody specific to Brain Derived Neurotrophic Factor (BDNF). Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Brain Derived Neurotrophic Factor (BDNF). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Brain Derived Neurotrophic Factor (BDNF) level in the sample or standard.;

欢迎！
请教各位大神，大家知道怎样对外泌体表面蛋白进行定量吗？看有文献用Western，还有裂解外泌体后用BCA进行定量，请问裂解后的外泌体蛋白定量应该是外泌体全部蛋白的吧，应该不只是表面蛋白（CD63这种）吧，还有这个BCA是怎么操作呢？有没有很可靠地能表示外泌体表面蛋白的定量方法？另外，怎么根据外泌体表面蛋白的量来算出外泌体的量呢？还有外泌体文献报道的外泌体浓度为μg/ml,这种浓度是怎样测出来的呢？还有表示外泌体10^9/ml这个测外泌体个数的应该是通过NTA吧？求大神分享外泌体定量的方法？急急急~

上次课程有句话让楼主印象深刻，Exosomesaresecretedbyallmammaliancelltypesinculture.
那如何去选择我们的实验样本？取样的时候需注意些什么？外泌体又如何保存呢？
上周四刚好赶上中秋，GCBI公众号也放了个小假，小编回来后赶忙补上上周高老师讲的外泌体样本收集与保存的课程，视频详情请戳：
外泌体的分离方法介绍
你研究的是哪种样本，需要特别注意哪些方面呢？一起来看看高老师的建议吧。
1细胞培养上清
2血液
受限于样本，血样一般取2ml。
那血浆or血清？
血浆=血液-血细胞
血清=血浆-纤维蛋白原-凝血因子
血清是血液凝固之后收集的液体，所以其中少了纤维蛋白原，凝血因子，以及多了很多凝血产物。纤维蛋白原可转化为纤维蛋白，具有凝血功能。
在凝血过程中血小板会分泌大量的外泌体，有研究发现血清中有接近50%的外泌体来自额外的分泌。
背后有啥解释呢？高老师在视频中有一一解答。
除了常见的细胞培养上清，血样，其他诸如唾液、鼻涕、尿液、乳汁及脑脊液如何收集呢？详情请戳视频。
课堂问答
1、微粒体和外泌体有什么区别？
微粒体是细胞破碎后，内膜系统的残体自发融合形成的小囊泡。外泌体是细胞分泌到胞外的直径为40-100nm的小囊泡，起源于内吞作用形成的内体。这两种小囊泡的起源和形成过程都不一样。
2、之前提取的外泌体忘记用PBS再洗一次，-80冻后1个月后再用PBS洗可以吗？
可以
3、采血后立即分离有没有文献支持？
有

写了外泌体RNA的中文综述，想投核心期刊，最好是容易接收，审稿费便宜的，求推荐一下，谢谢……
有没有前辈从事外泌体的研究，想从细胞上清中提取外泌体，但是因为实验室条件的因素，无法超离血清，想请教一下培养细胞的话还有没有什么别的方法？万分感激！！！！！！！！！！！！！！！！
