DATE: March 2023           Pubmed ID: 105785                   IF: 2.205

Isotope-labeled proteins are expected to be used as internal standard proteins in the field of protein quantification by isotope dilution mass spectrometry (ID/MS). To achieve the absolute quantification of Cystatin C (Cys C) based on ID/MS, we aims to obtain 15N isotope-labeled recombinant Cys C (15N-Cys C) protein.

Production and characterization of monoclonal antibodies against Toxoplasma gondii ROP18 with strain-specific reactivity

DATE: February 2020       p.p: 940 - 948    

The rhoptry kinase 18 of Toxoplasma gondii (TgROP18) has been identified as a key virulence factor that allows the parasite to escape from host immune defences and promotes its proliferation in host cells. Although much research is focused on the interaction between host cells and TgROP18,the development of monoclonal antibodies (mAbs) against TgROP18 has not been reported till date.

Mitochondrial Drp1 recognizes and induces excessive mPTP opening after hypoxia through BAX-PiC and LRRK2-HK2

DATE: November 2021       IF: 9.685

Mitochondrial mass imbalance is one of the key causes of cardiovascular dysfunction after hypoxia. The activation of dynaminrelated protein 1 (Drp1), as well as its mitochondrial translocation, play important roles in the changes of both mitochondrial morphology and mitochondrial functions after hypoxia. However, in addition to mediating mitochondrial fifission, whether Drp1 has other regulatory roles in mitochondrial homeostasis after mitochondrial translocation is unknown.
