生物活性

AMBA is a gastrin-releasing peptide receptor (GRPR, BB2, BRS-2) ligand with a human IC50 of 0.82 nM and a human Ki of 0.65 nM. AMBA binds to GRPR with high specificity and high affinity, and undergoes receptor-mediated endocytosis, which retains the conjugated radiometal in target cells. AMBA is applicable for the research of prostate cancer[1].

体外研究
(In Vitro)

AMBA (0.001-1000 nmol/L; 60 min) 对人 GRPR 受体具有高特异性和纳摩尔级亲和力,其 IC50 为 0.82 nmol/L,Ki 为 0.65 nmol/L[1]
AMBA (6.66 × 10-4 μmol (1 μg); 10 min) 可被 111In 高效放射性标记,在测试条件下的标记效率达 95.43%[1]

体内研究
(In Vivo)

111In-AMBA (0.37 MBq-12.2 MBq/4 μg; 静脉注射;单次给药) 在接种 PC-3 前列腺肿瘤的 SCID 小鼠中,于注射后 8 h 达到 3.87% ID/g 的肿瘤摄取峰值,肿瘤/肌肉比最高可达 11.79,表明其可有效靶向表达 GRPR 的肿瘤[1]

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.
