In vitro

Emtricitabine moderately reduces hepatocyte proliferation independent of effects on mtDNA in HepG2 human hepatoma cells. Emtricitabine plus tenofovir slightly reduced cell proliferation without affecting mitochondrial parameters. [1] Emtricitabine efficiently converts to their active metabolites in PBMCs and CEM cells. Emtricitabine combined with Tenofovir displays additive to synergistic activity against HIV replication in PBMCs and results in strongly synergistic anti-HIV activity in MT-2 cells against both wild-type and mutant virus. [2] Emtricitabine demonstrates antiviral activity against laboratory adapted strains of HIV-1 and HIV-2 in various cell system. Emtricitabine also exhibits antiviral activity in cell culture against feline and simian immuno-deficiency viruses (SIVs). Emtricitabine consistently exhibits up to 10-fold greater activity than lamivudine against all viruses tested in all T-cell lines. Emtricitabine generally demonstrates greater potency in vitro in human PBMCs than in MT-4 lines. [3] Emtricitabine also exhibits anti-HBV activity in vitro (EC50, 0.01–0.04 µM) that is comparable to the anti-HBV activity of 3TC. [4] Emtricitabine is approximately fourfold more active than 3TC in assays in the transformed T-cell line MT-4 infected with HIV-(1IIIB), whereas Zidovudine is more active than Emtricitabine. Emtricitabine, Lamivudine and Zidovudine are equally active against a panel of eight primary HIV-1 isolates from antiretroviral-naive subjects in PBMCs. [5]

Bio Calculators

Molarity Calculator

Molarity Calculator

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)

  • Mass
    Molecular Weight

*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).

Dilution Calculator

Dilution Calculator

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 )

  • C1

* 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.
