L-Thyroxine sodium
(Synonyms: Levothyroxine sodium; T4 sodium) 目录号 : GC61010A synthetic form of thyroxine
Cas No.:1955-3-8
Sample solution is provided at 25 µL, 10mM.
L-Thyroxine is a synthetic form of the thyroid hormone thyroxine.1,2,3 In vivo, L-thyroxine (0.9 and 2.7 μg) inhibits synthesis and release of thyrotropin induced by thyrotropin-releasing hormone from the anterior pituitary in mice.1 It also reverses decreases in levels of circulating thymic serum factor (FTS) and the number of T rosette-forming cells in an old age-induced mouse model of hypothyroidism.2,3 Formulations containing L-thyroxine have been used in the treatment of hypothyroidism.

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
