Catalog No.GC68996 Copy One-Click Copy Product Info

Donanemab es un anticuerpo monoclonal IgG1 humanizado. Donanemab se dirige Aβ42, depositado y a limpiar placas amiloides en el cerebro a través de la fagocitosis mediada por microglía. Donanemab se localiza principalmente en el plasma y el espacio extracelular y penetra en el cerebro a través de la barrera hematoencefálica para unirse a los depósitos de Aβ. Donanemab es un tratamiento eficaz para la enfermedad de Alzheimer.

Description of Donanemab

Donanemab es un anticuerpo monoclonal IgG1 humanizado. Donanemab se dirige Aβ42, depositado y a limpiar placas amiloides en el cerebro a través de la fagocitosis mediada por microglía. Donanemab se localiza principalmente en el plasma y el espacio extracelular y penetra en el cerebro a través de la barrera hematoencefálica para unirse a los depósitos de Aβ. Donanemab es un tratamiento eficaz para la enfermedad de Alzheimer [1-5].

En el modelo de ratón promotor del factor de crecimiento derivado de plaquetas-proteína precursora amiloide (PDAPP), los niveles de Aβ42 en el hipocampo y la corteza de los ratones se rejujeron significativamente después del tratamiento con Donanemab (1.5, 4, y 12.5mg/kg; sc; 6 mesess) [6].

In vivo Formulation Calculator (Clear solution) of Donanemab

Step 1: Enter information below (Recommended: An additional animal making an allowance for loss during the experiment)

mg/kg g μL

Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)

% DMSO % % Tween 80 % saline
%DMSO %

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
