生物活性

Lenercept (Ro 45-2081) is a recombinant fusion protein that consists of the soluble TNF-receptor (p55) linked to the Fc portion of human IgG1[1].

种属

Human

IC50 & Target

TNFR[1]

体外研究
(In Vitro)

Lenercept (TNFR-IgG) 在放线菌素 D (HY-17559) 处理的小鼠 L-M 细胞中阻断 TNF-α 和 TNF-β 的细胞溶解作用,IC50 分别为 0.5 μg/mL 和 1.5 μg/mL[2]

体内研究
(In Vivo)

Lenercept (Ro 45-2081) 抑制 Sephadex 诱导的大鼠肺损伤[1]
Lenercept (TNFR-IgG; 0.8-20 μg/mouse; i.v.; once) 当内毒素激发之前或之后不久给药时,可以预防或显著延迟内毒素诱导的小鼠致死率[2]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague-Dawley rats[1]
Dosage: 1 and 3 mg/kg
Administration: Intraperitoneal injection, 1 h before administration of Sephadex for the 24 h study or 1 h before and at 24 and 48 h after Sephadex for the 72 h study
Result: Inhibited the neutrophilia at 24 h after Sephadex. At 72 h after Sephadex, significantly reduced the neutrophil influx into bronchoalveolar lavage fluid (BALF) but had no inhibitory effect on eosinophil number.
Animal Model: 6- to 8-week-old female BALB/c mice, septic shock model[2]
Dosage: 0.8, 4 or 20 μg/mouse
Administration: IV, single dose
Result: Injection 0.5 h prior to Salmonella abortus-derived endotoxin (LD100 dose) administration prevented lethality at a dose of 20 μg per mouse and provided partial protection at lower doses. Injection of 10 μg per mouse provided significant protection 0.5 h before, 0.5 h after, or 1 h after endotoxin injection but little protection 2 h after endotoxin injection.

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.
