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。
'Precise quantitation of protein biomarkers in clinical tissue specimens is a prerequisite for accurate and effective diagnosis, prognosis, and personalized medicine. Although progress is being made, protein analysis from formalin-fixed and paraffin-embedded tissues is still challenging. In previous reports, we showed that the novel formalin-free tissue preservation technology, the PAXgene ... More
CaMKII and MEK1/2 inhibition time-dependently modify inflammatory signaling in rat cerebral arteries during organ culture.
Authors:Waldsee R, Eftekhari S, Ahnstedt H, Johnson LE, Edvinsson L,

PubMed ID:24886705
'Cerebral ischemia induces transcriptional upregulation of inflammatory genes in the brain parenchyma and in cerebral arteries, thereby contributing to the infarct development. The present study was designed to evaluate the involvement of calcium-calmodulin-dependent protein kinase (CaMKII) II and extracellular signal-regulated kinase1/2 (ERK1/2) on inflammatory mediators in rat cerebral arteries using ...

Altered MARCH1 ubiquination-regulated dendritic cell immune functions during the early stage of zymosan-induced multiple organ dysfunction syndrome (MODS) in mice.
Authors:Li F, Lu JY, Liu Q, Wang HW, Guo H,
Journal:Immunol Lett
PubMed ID:23305794
Using a zymosan-induced mouse model of multiple organ dysfunction syndrome (MODS), we previously found profound increases in spleen immune cells' expressions of ubiquitin and MHC-II molecules and increased CD11c+ dendritic cells (DCs) within 24h of zymosan injection. We postulated that the early stage of MODS altered DCs function via an ... More
Enhancement of cisplatin cytotoxicity by benzyl isothiocyanate in HL-60 cells.
Authors:Lee Y, Kim YJ, Choi YJ, Lee JW, Lee S, Chung HW,
Journal:Food Chem Toxicol
PubMed ID:22525867
Cis-diamminedichloroplatinum (II) (cisplatin) is one of the most widely used chemotherapeutic drugs, but its effectiveness is limited by tumor cell resistance and the severe side effects it causes. One strategy for overcoming this problem is the concomitant use of natural dietary compounds as therapeutic agents. Benzyl isothiocyanate (BITC) is a ... More
