(B-E) The % of GFP-positive cells upon compound treatment were determined for the indicated HIV-1 latency cell lines (B. J-LAT 6.3; C. JLAT 10.6; D. CA5; E. EF7). Results were normalized to DMSO control. Values represent the mean ± s.d. (n = 4-6). * p < 0.05, one-way ANOVA followed by Tukey’s multiplecomparison test

|Description||Levosimendan is a calcium sensitizer acting through calcium-dependent binding to cardiac troponin C (cTnC), provides treatment for heart failure.|
Levosimendan is a calcium sensitizer acting through calcium-dependent binding to cardiac troponin C (cTnC). Levosimendan at 3 μM decreases the value of Ca50 from 2.73μM to 1.19 μM. levosimendan exhibits its calcium sensitizing effect through calcium-dependent binding to the N-terminal domain of cTnC.  Levosimendan significantly hyperpolarizes resting potential of rat mesenteric arterial myocytes with an EC50 of 2.9 μM and maximal effect (19.5 mV) at 10 μM, probably through activation of a glibenclamide-sensitive K+ channel.  Levosimendan has inotropic and lusitropic actions in failing human myocardium, with average maximum increase in twitch tension of 47% at a levosimendan concentration of 0.8 μM.  Levosimendan causes rapid dose-dependent improvement in hemodynamic function in patients with decompensated heart failure. 
|In vivo||Levosimendan at low concentrations (0.03 to 0.1 μM) acts preferably as a Ca2+ sensitizer, whereas at higher concentrations (0.1 to 0.3 μmol/L) its action as a phosphodiesterase inhibitor contributes to the positive inotropic effect. |
|In vitro||DMSO||56 mg/mL (199.8 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
5% DMSO+40%PEG 300+5%Tween80+50%ddH2O
For best results, use promptly after mixing.
* 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.

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × 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 SDS / 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 SDS / 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.
