The animal core will breed transgenic mice which will be identified and characterized for use in Project 1:Design of alpha-chains that fully neutralize polymerization; Project 2: MRl and NIRS in SS patients and mice; Project 3: Sickle Cell Adhesion; and Project 4: Sickle vasocclusion: pleiotropism, epistasis, epigenetics. Our function will be mainly to provide assistance to investigators in the marking, identification, and record keeping of founders and their offspring. These mice will include the NY1KO mice that express exclusively human hemoglobins: HbS and three different levels of HbF; the BERK mice (originally described by Paszty et al) and BERK mice expressing HbF. Knockouts for iNOS, nNOS, vWF, and P-selectin will be bred into our sickle lines as will a variety of knockout and transgenic lines described in Project 4. Also included are mice that express exclusively HbC and exclusively HbA, as well as suitable control mice for all of the proposed experiments. This core also provides analytic services for other projects: protein identification and quantitation (HPLC, IEF, mass spec), red cell characterization (p50, intracellular polymerization, 2,3-DPG analysis), and red cell density distribution.

动物核心将培育转基因小鼠，这些小鼠将被鉴定和表征用于项目 1：设计完全中和聚合的 α 链；项目2：SS患者和小鼠的MRl和NIRS；项目3：镰状细胞粘附；项目4：镰状血管闭塞：多效性、上位性、表观遗传学。我们的职能主要是为调查人员提供创始人及其后代的标记、识别和记录保存方面的帮助。这些小鼠将包括仅表达人类血红蛋白的 NY1KO 小鼠：HbS 以及三种不同水平的 HbF； BERK 小鼠（最初由 Paszty 等人描述）和表达 HbF 的 BERK 小鼠。 iNOS、nNOS、vWF 和 P-选择素的敲除将被培育到我们的镰刀系中，项目 4 中描述的各种敲除和转基因系也将被培育。还包括仅表达 HbC 和仅表达 HbA 的小鼠，以及适合所有拟议实验的对照小鼠。该核心还为其他项目提供分析服务：蛋白质鉴定和定量（HPLC、IEF、质谱）、红细胞表征（p50、细胞内聚合、2,3-DPG 分析）和红细胞密度分布。
