(B)ΔISC response to forskolin observed in VX-661-treated CF HBE cells (*P = 0.0021, VX661 vs. vehicle) was prevented by chronic VX-770 treatment and significantly different from VX-661-treated cells (#P=0.0126, VX661 vs. VX661+VX770). (C) The response to CFTR inh-172 that was observed in VX-661-treated cells (*P = 0.0111, VX661 vs. vehicle) was significantly decreased in VX809+VX770 treated cells (#P = 0.0038, VX661 vs. VX661+VX770). Primary CF HBE cultures (ΔF508/ΔF508) were derived from 3 different patients, and 3-4 replicates were performed per patient.

|Description||VX-661 is a second F508del CFTR corrector and is believed to help CFTR protein reach the cell surface. Phase 2.|
VX-661, known as a CTFR corrector, allows F508del mutant channels to escape degradation and transit to the cell membrane.
|In vitro||DMSO||100 mg/mL (192.12 mM)|
|Water||slightly soluble or insoluble|
|Ethanol||slightly soluble or insoluble|
* 1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
