生物活性

Sodium dodecyl sulfate is an anionic surfactant commonly used as a detergent, emulsifier, and protein denaturant in various industrial processes, especially in the production of personal care products, cleaners, and laboratory reagents. Sodium dodecyl sulfate has unique chemical properties that make it an effective ingredient in many applications, helping to reduce surface tension and enhance cleaning power.

体外研究

Sodium dodecyl sulfate can be used as a pharmaceutical excipient. Pharmaceutical excipients or adjuvants refer to other chemical substances used in the pharmaceutical process, except for the drug components. Medicinal excipients generally refer to the inactive ingredients in drug formulations that can improve the stability, solubility, and processability of the drug formulation. Medicinal excipients can also affect the absorption, distribution, metabolism, and elimination (ADME) process of concomitant medications.

  • 1.

    请依序添加每种溶剂: 10% DMSO  →  90% (20% SBE-β-CD in saline)

    Solubility: ≥ 2.5 mg/mL (8.67 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (8.67 mM,饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD ⽣理盐⽔⽔溶液中,混合均 匀。

    请依序添加每种溶剂:10% DMSO → 90% corn oil

    Solubility: ≥ 2.5 mg/mL (8.67 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (8.67 mM,饱和度未知) 的澄清溶液,此方案不适用于实验周期在半个月以上的实验。

    以 1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
