Catalog No. T83714 Copy Product Info

Lupus autoantigen peptide (LAP), a derivative of the autoantigen La found in systemic lupus erythematosus (SLE) patients, spans amino acids 11-28 of La and functions as an antiviral peptide. It primarily blocks the hepatitis C virus (HCV) from interacting with internal ribosome entry site (IRES) trans-acting factors (ITAFs), notably the polypyrimidine tract-binding protein (PTB) and poly(rC)-binding protein 2 (PCBP2). In a Huh7 cell-based reporter assay, LAP at a concentration of 60 µM effectively hampers HCV IRES-mediated translation, a process reversible by adding recombinant forms of PTB and PCBP2.

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 µL Tween 80 and mix well until fully clarified.

3) Add 450 µL Saline,PBS or ddH₂O and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
