In Vitro |
Addition of Tween 20 can modify lignin surface properties to change its hydrophobicity, hydrogen bonding ability and surface charges, thus reducing the non-productive adsorption of proteins[1]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. |

Solvent & Solubility |
In Vitro:
DMSO : 50 mg/mL (ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol) Concentration (start) × Volume (start) = Concentration (final) × Volume (final) This equation is commonly abbreviated as: C1V1 = C2V2 In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:

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.
