一般說明

瘦素基因(LEP)位于人类染色体7q32.1上。编码的蛋白质是通过成熟脂肪细胞合成和分泌的非糖基化多肽。瘦素主要表达于白色脂肪组织、胎儿组织、骨骼肌、软骨细胞、胃主细胞、胎盘、卵巢和多种免疫细胞中。在其他成人组织中不表达或表达水平极低。人瘦素与小鼠瘦素的相似性达85%,与大鼠瘦素有84%,而小鼠和大鼠瘦素之间则有96%的相似性。

特異性

瘦素抗体与瘦素特异性反应。

免疫原

合成肽对应人/小鼠瘦素氨基端(氨基酸残基22-40)。

應用

兔源抗-瘦素单克隆抗体可用于:
  • 免疫印迹
  • 免疫组织化学
  • 免疫细胞化学
  • 酶联免疫吸附试验(ELISA)

生化/生理作用

瘦素是一种由脂肪细胞分泌的激素,可调节能量稳态、炎症和神经内分泌过程、突触形成和记忆增强(memory condensation)。瘦素通过瘦素受体ObR和LepR介导生理作用。瘦素是肥胖症的主要调控因子,可直接作用神经元网络调节摄食、代谢和胃动力。瘦素作用的发挥途径包括JAK/STAT(Janus激酶/信号转导及转录激活蛋白)、磷酸肌醇3-激酶(PI3K)和c-Jun氨基末端激酶(JNK)。
瘦素是可诱发营养摄食、产热、新陈代谢、生殖和造血的多效性血清细胞因子。据推测,瘦素可能是“饱腹感感因子”,因为在ob/ob小鼠中(自发性肥胖突变纯合体),该因子的缺失与过食和肥胖有关。ob/ob小鼠注入瘦素后食量减少,并最终导致体重下降,说明瘦素可能参与食欲调节。不过根据研究,其作用机制比简单的食欲抑制更为复杂。

外觀

磷酸盐缓冲液,含1%牛血清白蛋白和15 mM叠氮化钠。

準備報告

抗体通过肽-琼脂糖亲和分离。

儲存和穩定性

若需连续使用,可在2-8°C下保存最长一个月。若需延长储存时间,可将溶液分装并冷冻。不建议反复冻融。不建议在无霜冰箱中储存。如果长期储存后发生轻微浑浊,请在使用前通过离心澄清溶液。
