An experimental investigation of pulsed Nd3+: YAG active-passive mode-locked laser system is reported. The pulse width measured by the noncollinear SHG technique was about 40 psec. 报导了Nd~(3+):YAG激光器的主被动锁模实验,利用二次谐波法测得脉冲宽度约为40ps。
Conclusion We have constructed successfully the recombinant PD-L1/ pSec/ WG plasmid and purified the protein PD-L1, based on which we can prepare mAb that aims directly at the protein PD-L1. 结论成功地构建了PD-L1/pSec/WG重组质粒,纯化出PD-L1蛋白,可进行下一步mAb制备,进一步研究其功能。
