Romiplostim

Revisión del cliente

Based on 1 Customer Validation

Romiplostim is an Fc-peptide fusion protein mimetic of TPO (thrombopoietin protein) and also a c-Mpl agonist. Romiplostim binds to c-Mpl, stimulates megakaryocyte-mediated thrombopoiesis, and activates the same downstream signaling pathways as endogenous TPO. Romiplostim is applicable to research related to hematopoietic acute radiation syndrome and chronic immune thrombocytopenia.

IC₅₀ & Target

TPO (thrombopoietin protein)

Parmacokinetics

Species	Dose	Route	T_max	C_max	T_1/2	AUC_0-t
Mice^[1]	30 μg/kg	s.c.	12 h	6 ng/mL	24.3 h	228 ng·h/mL
Mice^[1]	300 μg/kg	s.c.	4 h	201 ng/mL	29.9 h	8912 ng·h/mL

In Vivo

Romiplostim (3-300 μg/kg; s.c.; single dose at 24-26 h post-irradiation; daily on Days 1-3 post-irradiation; daily on Days 1-5 post-irradiation) provides a statistically significant ~40% increase in 30-day survival and hastens platelet recovery when administered as a single subcutaneous dose of 30 or 100 μg/kg 24 hours post-6.8 Gy total body irradiation, with no additional benefit from repeat dosing or co-administration with pegfilgrastim^[1].

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

Animal Model:

C57BL/6J (male and female, 11-12 weeks of age, total body irradiation with 6.8 Gy X-rays)^[1]
Dosage:

3 μg/kg; 10 μg/kg; 30 μg/kg; 100 μg/kg; 300 μg/kg
Administration:

Result:

Resulted in 41% 30-day survival (3 μg/kg single dose, 6.8 Gy model).
Resulted in 38% 30-day survival (10 μg/kg single dose, 6.8 Gy model).

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
