Heterozygous: one band at 439 bp with primers F1/R1 and one band at 219 bp with primers F2/R2;

Abbr.. M, DNA marker; HE, heterozygous; WT, wild type.

Fig8. In vivo evaluation of TFR1-targeting therapeutic agents in hTFR1 knockin mice.

hTFR1/CD71 knockin mice were injected with a control antibody (10mg/kg) and an antibody (10 mg/kg) against human TFR1 via i.v. injection. 

Brain tissues and serums were taken after 18 hr post administration. Brain concentrations, serum concentrations and brain-to-serum ratio of antibodies were quantified. As shown in the figure, hTfr binding antibody exhibited higher serum clearance and enhanced brain exposure.

Tamoxifen诱导Cre-ERT2小鼠 使用指南

Cre-ERT2在无Tamoxifen诱导的情况下,在细胞质内处于无活性状态;当Tamoxifen诱导后,Tamoxifen的代谢产物4-OHT(雌激素类似物)与ERT结合,可使Cre-ERT2进核发挥Cre重组酶活性。
