嵌段共聚温敏亲和色谱固定相的制备及其对抗体的分离纯化

抗体药物在癌症治疗和免疫诊断中起着重要作用,但抗体的分离纯化通常采用酸性洗脱,易导致抗体聚集失活等问题。本研究以硅胶为基质,以温敏嵌段聚合物聚[(N-异丙基丙烯酰胺)-b-4-乙烯基吡啶](P[NIPAM-b-4VP])为间隔臂,以4-巯基乙基吡啶(M... 详细信息

抗体药物在癌症治疗和免疫诊断中起着重要作用,但抗体的分离纯化通常采用酸性洗脱,易导致抗体聚集失活等问题。本研究以硅胶为基质,以温敏嵌段聚合物聚[(N-异丙基丙烯酰胺)-b-4-乙烯基吡啶](P[NIPAM-b-4VP])为间隔臂,以4-巯基乙基吡啶(MEP)为配基,制备了一种嵌段共聚温敏亲和色谱固定相SiO_(2)-P[NIPAM-b-4VP]-MEP,并以牛血清白蛋白(BSA)和γ-球蛋白为模型蛋白,对制备的温敏亲和色谱固定相的色谱性能进行了表征。分别考察了流动相盐浓度和温度对二者分离性能的影响。结果表明,在40℃时该固定相只选择性保留γ-球蛋白,而不保留BSA;在5℃时采用含0.6 mol/L NaCl的Tris-HCl(pH 8.0)缓冲溶液进行洗脱,γ-球蛋白的质量回收率为92.7%。该固定相对γ-球蛋白的吸附量为(71.5±2.1)mg/g(n=3),是传统温敏亲和色谱固定相SiO_(2)-PNIPAM-MEP的2倍。将该固定相用于人血清中IgG的分离纯化,仅通过改变流动相温度和盐浓度即可一步实现对抗体的分离纯化,纯度大于97.4%±0.7%。上述结果表明该温敏亲和色谱固定相不仅对抗体具有特异的选择性,而且洗脱条件温和,绿色环保,从根本上解决了传统亲和色谱采用酸性洗脱易使抗体蛋白变性失活的难题。该技术在抗体药物的分离纯化和工业生产中具有重要的应用价值。

Surface-plasmonic sensor using a columnar thin film in the grating-coupled configuration [Invited]

引用

Chinese Optics Letters 2021年第8期19卷 121-129页

作者： Kiran mujeeb Muhammad Faryad Akhlesh Lakhtakia Julio V.urbina Department of Electronics Quaid-i-Azam UniversityIslamabad 45320Pakistan Department of Physics Lahore University of Management SciencesLahore 54792Pakistan Department of Engineering Science and Mechanics The Pennsylvania State UniversityUniversity ParkPennsylvania 16802USA Department of Electrical Engineering The Pennsylvania State UniversityUniversity ParkPennsylvania 16802USA

The excitation of a surface-plasmon-polariton(SPP) wave guided by a columnar thin film(CTF) deposited on a one-dimensional metallic surface-relief grating was investigated for sensing the refractive index of a fluid infiltrating that CTF. The Bruggemann homogenization formalism was used to determine the relative permittivity scalars of the CTF infiltrated by the fluid. The change in the refractive index of the fluid was sensed by determining the change in the incidence angle for which an SPP wave was excited on illumination by a p-polarized plane wave, when the plane of incidence was taken to coincide with the grating plane but not with the morphologically significant plane of the CTF. Multiple excitations of the same SPP wave were found to be possible, depending on the refractive index of the fluid, which can help increase the reliability of results by sensing the same fluid with more than one excitation of the SPP wave.
