以下是一些建议:
o 在获取板之前,在 Luminex 仪器上运行校准和验证珠。
o 查看仪器设置并确保它们适合正在运行的检测(调整针高,确保选择正确的珠门和正确的 DD 设置)。
o 在仪器上采集前摇动板以重新悬浮珠子。
o 将珠子涡旋 30 秒,然后再将它们添加到板中。
o 清洗:在清空板之前,不要忘记将板放在手持式磁性洗板机上约 2 分钟。
这种模式表明样本基质效应。以下是一些建议:
o 确认样品已澄清且不含碎片和脂质(建议离心 5-10 分钟)。
o 确认血清、血浆样品的样品与测定稀释剂的比例至少为 1:1。对于细胞裂解物或组织匀浆,确认样品已在测定缓冲液中适当稀释,以将裂解缓冲液中的去污剂浓度降低至≤0.01%。对于其他样品类型,可能需要进一步的样品优化。
Diverse action of lipoteichoic acid and lipopolysaccharide on neuroinflammation, blood-brain barrier disruption, and anxiety in mice.

PubMed ID:27751870
Microbial metabolites are known to affect immune system, brain, and behavior via activation of pattern recognition receptors such as Toll-like receptor 4 (TLR4). Unlike the effect of the TLR4 agonist lipopolysaccharide (LPS), the role of other TLR agonists in immune-brain communication is insufficiently understood. We therefore hypothesized that the TLR2 ...

Intestinal Epithelial Cell Autophagy Is Required to Protect against TNF-Induced Apoptosis during Chronic Colitis in Mice.
Authors:Pott J, Kabat AM, Maloy KJ
Journal:Cell Host Microbe
PubMed ID:29358084
Genome-wide association studies have linked polymorphisms in the autophagy gene ATG16L1 with susceptibility to inflammatory bowel disease (IBD). However, the cell-type-specific effects of autophagy on the regulation of chronic intestinal inflammation have not been investigated. Here, we assessed the effect of myeloid-specific or intestinal epithelial cell (IEC)-specific deletion of Atg16l1 on ... More
