Meteorin-like protein, Subfatin, METRNL.
METRNL or 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.
METRNL Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain (a.a 46-311) containing 276 amino acids including a 10 a.a N-terminal His tag. The total molecular mass is 31.2kDa (calculated).
METRNL filtered (0.4 µm) and lyophilized from 0.5mg/ml in 50mM acetate buffer, 5% trehalose (w/v) and 1mM DTT, pH 4.
It is recommended to add 0.1M acetate buffer, pH 4 to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely.
Greater than 95.0% as determined by SDS-PAGE.
