How to prepare FFPE samples?
FFPE (Formalin-Fixed Paraffin-Embedded) preparation includes a series of steps. First, the fresh collected tissue is immersed in a formaldehyde (formalin) solution to fix the cellular structures. This fixed tissue is then dehydrated with a series of alcohol dilutions and cleared by using a clearing agent. After that, the tissue is embedded in liquid paraffin wax. Finally, after the wax solified, the tissue wax block is sectioned into thin slices using a microtome. For further analysis, these since slices can be mounted onto a coverglass. To learn more about FFPE samples, I recommend to check out the FAQ on our website where we offer human tissue samples: centralbiohub.de/biospecimens/cancer-samples/ffpe-samples
How do you prepare a 5 percent potassium iodide solution?
To prepare a 5% potassium iodide solution, weigh 5 grams of potassium iodide and dissolve it in 100 mL of water. Stir until the potassium iodide is completely dissolved to achieve a 5% solution.
How much solute is needed to prepare 150mL of a 40.0 percent lithium nitrate solution?
To prepare a 40.0% lithium nitrate solution, 60mL of the solution would be solvent (water) and 90mL would be solute (lithium nitrate). Therefore, you would need 90mL of lithium nitrate to prepare 150mL of the 40.0% solution.
How can you prepare 1N H2SO4 from H2SO4 95 percent?
To prepare 1N H2SO4 from 95% H2SO4, you would first need to dilute the 95% H2SO4 with water by adding the appropriate amount of water to achieve the desired concentration. To calculate the volume of 95% H2SO4 needed to make 1N solution, you need to use the formula: (Normality of stock solution) * (Volume of stock solution) = (Normality of diluted solution) * (Volume of diluted solution). Adjust the volumes accordingly to prepare the desired 1N solution.
How does one prepare 10 percent neutral buffered formalin?
To prepare 10 percent neutral buffered formalin, start by mixing 90 mL of distilled water with 10 mL of formaldehyde solution (37-40% concentration). Add buffering agents, typically sodium phosphate monobasic (3.6 g) and sodium phosphate dibasic (4.4 g), to maintain neutral pH. Adjust the final volume to 1 liter with distilled water, ensuring thorough mixing. It's essential to use appropriate safety precautions, as formaldehyde is a hazardous substance.
How much water must be added to 425 g of formaldehyde to prepare a 40.0 percent by mass solution of formaldehyde?
To calculate the amount of water needed, first determine the mass of formaldehyde in the final solution. Since the solution is 40.0% formaldehyde by mass, the mass of formaldehyde is 40.0% of the final solution mass. Subtract the mass of formaldehyde in 425 g from this value to find the mass of water needed to prepare the solution.
