| 背景资料 | Cephalothin binds to and inactivates penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. Cephalothin Sodium is the sodium salt form of cephalothin, a semisynthetic, beta-lactam, the first-generation cephalosporin antibiotic with bactericidal activity. PBPs participate in the terminal stages of assembling the bacterial cell wall, and in reshaping the cell wall during cell division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis. |

文献和实验1. 前言 如能通过电转移或其他相关技术将蛋白样品从凝胶相有效转移到适合于气相测序 ( gas-phase sequencing) 的其他介质上时，则 2D 凝胶分离的蛋白可进行 Edman 测序 [1] 。首先，皮摩尔数量级的蛋白通过 2D-PAGE 分离 [2]，然后经电转移从 2D-PAGE 凝胶上转移到 PVDF 膜上，再通过 Edman 测序法进行蛋白质的氨基酸测序。蛋白质 N 端顺序测定法—— Edman 降解是非常灵敏的测序方法（只需 1~5 μg 的蛋白质）。但是当出现

electrophoresis (DIGE), samples are labelled separately then combined and run on the same 2D gel minimizing experimental variation and greatly facilitating spot matching. When three CyDyes (Cy2, Cy3, and Cy5) have been used, three images of the gel are captured
Purification and Analysis of Variant and Modified Histones Using 2D PAGE
Two-dimensional (2D) polyacrylamide gel electrophoresis (PAGE) systems employing combinations of acetic acid/urea (AU), acetic acid/urea/Triton X-100 (AUT) and sodium dodecyl sulfate (SDS) gel formulations are uniquely effective
