Pepsinogen C / PGC抗体 Background
Gastricsin, also known as Pepsinogen C and PGC, is a secreted which belongs to thepeptidase A1 family. PGC / Gastricsin hydrolyzes a variety of proteins. PGC / Gastricsin is more restricted specificity than pepsin A, but shows preferential cleavage at Tyr-|-Xaa bonds. It has high activity on hemoglobin. PGC / Gastricsin is an aspartic proteinase that belongs to the peptidase family A1. It is a digestive enzyme that is produced in the stomach and constitutes a major component of the gastric mucosa. This protein is also secreted into the serum. It is synthesized as an inactive zymogen that includes a highly basic prosegment. This enzyme is converted into its active mature form at low pH by sequential cleavage of the prosegment that is carried out by the enzyme itself. Serum levels of this PGC / Gastricsin are used as a biomarker for certain gastric diseases includingHelicobacter pylorirelated gastritis.

文献和实验Clonality - X Chromosome Inactivation Assay
can utilize X chromosome inactivation (methylation) to determine the clonality status of a tumor or premalignant lesion in females. The technique is based on a methylation-sensitive restriction enzyme and analysis of a polymorphic locus on the X chromosome
抗体的结构决定了其对应的功能,同一抗体的V区和C区的氨基酸组成和顺序不同,决定了其功能上的差异。V区和C区的组成和结构,决定了抗体的生物学功能。 图1:抗体的主要功能(图片来源:Abbas et al: Cellular and Molecular Immunology, 7e.) 1、特异性识别功能 抗体可以通过其结构上的可变区域与抗原结合,同时,具有极高的特异性。这种特异性识别功能可以使抗体识别和结合到感染的病原体,肿瘤细胞等不同种类的分子,帮助免疫系统识别并定位到这些分子,进而启动
脾细胞与小鼠骨髓瘤细胞(P3-X63/Ag8)融合,融合的细胞既获得了亲代脾细胞分泌特异性抗体的特性,又具有骨髓瘤细胞大量繁殖的能力,成为一种既能分泌特异性抗体又能长命的杂交瘤细胞。该技术为抗体的分子生物学研究提供了全新的手段。极大地促进了免疫学,遗传学,分子生物学的快速发展。 但传统抗体目前也面临诸多问题,如: 每使用一管新抗体都需要进行滴定测试; 多种同型对照,实验设计繁琐; 需要添加Fc阻断试剂; 抗体不佳,阳性细胞群不明显; 抗体作为细胞生物学和生物化学中最重要的试剂之一,科学界每年在这类
