Recombinant Mouse PDGF-CC

Isolation and Culture of Mouse Pancreatic Islets for Ex Vivo Imaging Studies with Trappable or Recombinant Fluorescent Probes

with a Ca2+ -free medium or with trypsin/dispase. The latter facilitates the introduction of recombinant or trappable probes and microimaging studies of, for example, changes in cytosolic-free Ca2+ concentration or the dynamics of individual organelles

Purification of Recombinant Chemokines from E. coli

since they all form two disulfides between Cys-1 and 3, and Cys2 and 4, whether they belong to the α or CXC or β or CC subclass. Molecular modeling of the two chemokines that deviate from the motif, the C chemokine lymphotactin which lacks a disulfide, and the CX3 C

异表型鼠 allophenic mouse

异表型鼠 allophenic mouse 系实验中形成的小鼠的遗传嵌合体的一种，是由 B.Mintz提出的。在胚胎发生初期阶段以后的整个发育过程，所有组织或一部分组织中，作为基础的基因型已知有两个或更多的等位基因（基因型确知）存在于不同细胞中，因而不同细胞表型同时共存于一个个体内，这种现象称为异表型（ allophenism）。具有这一性状的个体统称为异表型体（ allopheny），目前这一术语在小鼠中使用最多。形成异表型鼠的实验操作方法是：（ 1）先选择标记基因（例如支配表皮黑色
