|Description||Neomycin sulfate is an aminoglycoside antibiotic, used to treat bacteria infections.|
Neomycin interacts preferentially with the ribozyme-substrate complex and that this interaction leads to a reduction in the cleavage rate by stabilizing the ground state of the complex and destabilizing the transition state of the cleavage step.  Neomycin effects a conformational change in the structure of trans-activating region (TAR) that can be detected by circular dichroism spectroscopy. Neomycin acts as a noncompetitive inhibitor that can bind to the Tat-TAR complex and increase the rate constant (koff) for dissociation of the peptide from the RNA.  Neomycin is the most effective aminoglycoside (groove binder) in stabilizing a DNA triple helix. Neomycin stabilizes TAT, as well as mixed base DNA triplexes, better than known DNA minor groove binders (which usually destabilize the triplex) and polyamines. Neomycin shows a preference for stabilization of TAT triplets but can also accommodate CGC(+) triplets.  Neomycin induces a concentration- and voltage-dependent partial block from both the cytosolic and luminal faces of the channel. Neomycin has a greater affinity for the luminal site of interaction than the cytosolic site: zero-voltage dissociation constants (Kb(0)) are respectively 210.20 nM and 589.70 nM for luminal and cytosolic block. Neomycin also exhibits voltage-dependent relief of block at holding potentials >+60 mV.

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.
