生物活性

Zevontabart (MYTX-011 Antibody) is a pH-dependent anti-c-MET ADC. Zevontabart modulates the trafficking process of c-MET to reduce receptor recycling, and enhances its own endocytosis and accumulation in c-MET-expressing cells. Zevontabart induces cytotoxicity in solid tumor cells and exerts anti-tumor activity in a non-small cell lung cancer xenograft mouse model. Zevontabart can be used in studies related to non-small cell lung cancer, with its corresponding isotype control being Human IgG1 kappa, Isotype Control (HY-P99001)[1].

体外研究
(In Vitro)

Zevontabart (50 nmol/L; 120 s association, 300 s dissociation) 可与重组人源 c-MET 发生 pH 依赖性结合,与中性 pH 7.4 相比,在内体溶酶体 pH 5.4 条件下解离速度更快[1]
Zevontabart (10 nmol/L; 0.5-3 h) 在 NCI-H1975 c-MET+ 非小细胞肺癌 (NSCLC) 细胞的溶酶体中的高度积累[1]
Zevontabart (25 nmol/L; 30 min) 在 EBC-1 c-MET+ 癌细胞中与 Rab4+ 快速循环内体的共定位水平低[1]

Immunofluorescence[1]

Cell Line: NCI-H1975 (c-MET+ NSCLC) cells transfected with LAMP1-RFP (lysosomal marker)
Concentration: 10 nmol/L
Incubation Time: 30 min, 1 h, 3 h
Result: Showed equivalent colocalization with LAMP1-RFP+ lysosomes to the parent mAb at all time points, but exhibited significantly higher fluorescence intensity within lysosomes relative to the parent mAb.

Immunofluorescence[1]

Cell Line: EBC-1 (c-MET+ cancer) cells transfected with Rab4-mRuby (fast-recycling endosome marker)
Concentration: 25 nmol/L
Incubation Time: 30 min
Result: Showed significantly lower colocalization with Rab4-mRuby+ fast-recycling endosomes relative to the parent mAb.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
