Recombinant Human METRNL Protein (E. coli, N-His) 别名：Meteorin-like protein; Subfatin; 重组人METRNL 蛋白 (E. coli, N-His)
METRNL (Meteorin-like protein) is a hormone, released after physical activity (in skeletal muscle) or exposure to cold (in adipose tissue), that induces energy rate. METRNL stimulates energy rate correlate with white fat browning and raise glucose tolerance. The protein stimulates different types of immune cells to enter the fat tissue and start their prothermogenic actions.

生物活性
METRNL (Meteorin-like protein) is a hormone, released after physical activity (in skeletal muscle) or exposure to cold (in adipose tissue), that induces energy rate. METRNL stimulates energy rate correlate with white fat browning and raise glucose tolerance. The protein stimulates different types of immune cells to enter the fat tissue and start their prothermogenic actions.
The recombinant Human METRNL expressed a DNA sequence encoding the Human METRNL (Q641Q3) (Gln46-Asp311) with polyhistidine tag at the N-terminus.
Accession: Q641Q3
Predicted molecular weight: 32.25 kDa
Endotoxin < 1 EU/µg
Lyophilized from a solution in PBS pH 7.4, 0.02% NLS, 1mM EDTA, 4% Trehalose, 1% Mannitol.
实验参考
建议您制定动物给药及实验方案时，尽量参考已发表的相关实验文献（溶剂种类及配比众多，简单地溶解目的化合物，并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题，未必能保证目的化合物在动物体内充分发挥生物学效用）。
体内实验的工作液，建议您现用现配，当天使用；如在配制过程中出现沉淀、析出现象，可以通过超声和（或）加热的方式助溶。
切勿一次性将产品全部溶解。
请在下面的计算器中，输入您的动物实验相关数据并点击计算，即可得到该实验的总需药量和工作液终浓度。
例如您给药剂量是10 mg/kg，平均每只动物的体重为20 g，每只动物的给药体积是100 μL，动物数量为20只，则该动物实验的总需药量为4 mg，工作液终浓度为2 mg/mL。
1：鉴于实验过程的损耗，建议您至少多配1-2只动物的量；
2：为该产品最终给药时的浓度。
