光学蛋白质芯片法测定甲胎蛋白的初步研究

open access: yes, 2009
采用微流道反应器系统,优化甲胎蛋白单克隆抗体浓度,并装配在醛基改性后的硅片表面上,经牛血清白蛋白封闭后形成检测AFP芯片阵列。通过制作AFP浓度梯度标准曲线标定光学蛋白质芯片,实现肿瘤标志物AFP的检测,结果表明,该方法的最低测定浓度可以达到1.0ng/mL,变异系数为3.1%,回收率在94.4 105.0%之间,与人纤维蛋白原的交叉反应率≤0.25%、与1%葡萄糖≤0.08%、与人源IgG≤0.16%和与人血清白蛋白≤0.20%,说明光学蛋白质芯片技术检测AFP,灵敏度高、重复性好、操作简便 ...

一种改性蛋白芯片表面的方法

open access: yes, 2007
本发明涉及一种改性蛋白芯片表面的方法,其特征在于用常规方法在蛋白质芯片的基片上先固定一层小分子量的蛋白质分子,再固定待固定的蛋白质分子。所述的小分子量的蛋白质分子的分子量为1×103~9×105道尔顿。该方法可以改善蛋白质芯片表面的特性:一方面,小分子量的蛋白质分子覆盖在蛋白质芯片的表面,保证了待固定的蛋白质分子的生物活性,同时也抑制了待固定的蛋白质分子在固体表面上的非特异性吸附;另一方面,小分子量的蛋白质分子的带有氨基、羧基、羟基、巯基等活性基团的极性氨基酸残基多位于蛋白质分子表面 ...

Predictive value of gB2 antibodies for maternal–fetal transmission after primary cytomegalovirus infection treated with valacyclovir

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 455-460, April 2026.
ABSTRACT Objective To estimate the residual risk of maternal–fetal transmission after primary cytomegalovirus (CMV) infection in the periconceptional period or the first trimester in women treated with valacyclovir, and to assess whether the presence of glycoprotein B2 (gB2)‐specific immunoglobulin (Ig)‐G antibodies on immunoblot analysis refines fetal

Efficacy of Der f 2/Zen 1‐LAMP1 Plasmid‐Based Vaccine Immunotherapy in Dogs With Atopic Dermatitis: A Proof‐of‐Concept Study

open access: yesVeterinary Dermatology, Volume 37, Issue 2, Page 306-318, April 2026.
Background: DNA‐based vaccination rapidly induces strong cellular and humoral immune responses, which may be enhanced by inclusion of lysosomal‐associated membrane protein‐1 (LAMP). Objectives: This proof‐of‐concept study evaluated the efficacy and safety of a Der f 2/Zen 1‐LAMP‐based DNA vaccine immunotherapy in client‐owned dogs with nonseasonal AD ...

Lipid Nanoparticles Delivering ClpP‐mRNA Suppress Pyroptosis and Senescence in Intervertebral Disc Degeneration via mTOR/BNIP3‐Activated Mitophagy

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

血清白蛋白、尿微量白蛋白在妊高征患者中表达和临床诊断意义

open access: yesZhongguo shiyan zhenduanxue, 2012
目的探讨血清白蛋白及尿微量白蛋白检测在妊高征早期诊断中的临床意义。方法选择2008年1月到2009年12月在我院门诊收治的孕8周左右孕妇126例,收集所有患者孕妇清晨的尿量。采用放射免疫法测定尿微量白蛋白(mAlb)的排泄量,采用电泳法测定血清白蛋白(ALB).分别检测12周、16周、20周、36周孕妇尿微量白蛋白和血清白蛋白。患者按最终孕妇是否发生妊高征分成正常妊娠组(71例)和妊高征组(55例)。分析检测结果。结果 在第12周正常妊娠组尿微量白蛋白为12.38±5.12mg/L ...

去除高丰度蛋白质对脑脊液差异蛋白鉴定的影响

open access: yesZhongguo shiyan zhenduanxue, 2013
目的探讨去除高丰度蛋白质对脑脊液差异蛋白鉴定的影响。方法应用Cibacron-blue-3G-A亲和层析柱去除脑脊液中含量最多的高丰度蛋白质-白蛋白,然后对去除白蛋白前后的脑脊液样本,以及经过Cibacron-blue-3G-A亲和层析柱吸附后洗脱下来的脑脊液样本,分别进行双向凝胶电泳,对比分析各样本差异蛋白点的分布情况。结果 Cibacron-blue-3G-A亲和层析柱通过结合去除了脑脊液中的大部分白蛋白,但是同时也去除了一些其它可能有意义的蛋白质,而且在去除白蛋白后 ...
