The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To make 100 mL of TBST buffer from 1X TBS<\/strong> and 0.1% Tween-20<\/strong>, follow these calculations:<\/p>\n\n\n\n

Step 1: Understanding the components<\/strong><\/h3>\n\n\n\n
    \n
  • 1X TBS<\/strong> is already at the correct concentration, so you do not need to dilute it further.<\/li>\n\n\n\n
  • Tween-20<\/strong> needs to be added to a final concentration of 0.1% (v\/v)<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Step 2: Calculate Tween-20 volume<\/strong><\/h3>\n\n\n\n
      \n
    • 0.1% Tween-20<\/strong> means 0.1 mL of Tween-20 per 100 mL of solution<\/strong>.<\/li>\n\n\n\n
    • Convert to microliters:
      [
      0.1 \\text{ mL} = 100 \\text{ \u00b5L}
      ]<\/li>\n<\/ul>\n\n\n\n

      Step 3: Prepare the solution<\/strong><\/h3>\n\n\n\n
        \n
      1. Measure 100 mL of 1X TBS<\/strong>.<\/li>\n\n\n\n
      2. Add 100 \u00b5L of Tween-20<\/strong>.<\/li>\n\n\n\n
      3. Mix well by gentle stirring or inversion.<\/li>\n<\/ol>\n\n\n\n
        \n\n\n\n

        Explanation (300 words)<\/strong><\/h2>\n\n\n\n

        TBST (Tris-Buffered Saline with Tween-20) is a commonly used buffer in biochemical applications, particularly in Western blotting<\/strong> and ELISA<\/strong> to wash membranes and prevent non-specific binding. The key components of TBST are TBS (Tris-buffered saline)<\/strong>, which maintains pH stability, and Tween-20<\/strong>, a detergent that helps reduce background noise by preventing non-specific protein binding.<\/p>\n\n\n\n

        In this case, we are starting with 1X TBS<\/strong>, which means it is already at its working concentration. Unlike working with 10X TBS<\/strong>, where dilution calculations are required, 1X TBS does not require further dilution. Our only step is to add Tween-20.<\/p>\n\n\n\n

        Since Tween-20 is typically used at a 0.1% (v\/v) concentration<\/strong>, we calculate its volume using the formula:
        [
        \\text{Volume of Tween-20} = \\text{Final Volume} \\times \\text{Desired Percentage}
        ]
        [
        = 100 \\text{ mL} \\times 0.1\\% = 0.1 \\text{ mL} = 100 \\text{ \u00b5L}
        ]<\/p>\n\n\n\n

        Once the Tween-20 is added, the solution should be mixed gently to ensure even distribution. It is best to store TBST at 4\u00b0C<\/strong> if not used immediately.<\/p>\n\n\n\n

        This simple preparation ensures consistency and reproducibility in experiments where TBST is required as a washing buffer<\/strong>, improving the reliability of Western blot and ELISA results.<\/p>\n\n\n\n
