It dissolves the phospholipid bilayer of cell membranes by forming water-soluble complexes with them. Once the cell membranes are degraded, the cell contents flow out & create a soup of dissolved membranes, cellular proteins, DNA, & other contents.

What is the scientific name for when cells swell and burst?
The scientific term for when cells swell and burst is "lysis". This can occur due to factors such as osmotic imbalance or physical damage to the cell membrane.
Role of ctab in the lysis of cell membrane?
CTAB, or cetyltrimethylammonium bromide, is a cationic surfactant that disrupts the cell membrane by interacting with the negatively charged phospholipid bilayer. It solubilizes lipids and proteins, leading to cell lysis. CTAB is commonly used in DNA extraction protocols to liberate nucleic acids from cells by disrupting the cell membrane.
What is the lysis solution made of?
The lysis solution typically contains detergents or surfactants that disrupt cell membranes, releasing cellular contents. It may also contain salts, enzymes, or other reagents to stabilize proteins or nucleic acids during cell lysis. The specific composition of the lysis solution can vary depending on the type of cells being lysed and the intended downstream application.
What solution does crenation occur in?
Crenation occurs in a hypertonic solution, where the concentration of solutes outside the cell is higher than inside, causing water to leave the cell, leading to shrinkage and deformation of the cell.
Why does the nattharick's solution not do the lysis of white blood cells?
The Nattharick's solution does not cause lysis of white blood cells because it is an isotonic solution, meaning it has the same osmotic pressure as the cells. This balance in osmotic pressure prevents the solution from causing the white blood cells to take up too much water or lose too much water, which would result in cell lysis.
What are the ingredients in the lysis solution used for cell lysis?
The ingredients in the lysis solution used for cell lysis typically include detergents, salts, and enzymes. These components work together to break down the cell membrane and release the cellular contents for further analysis.
What is the difference between lysis and lysate?
Lysis is the physical breakdown of a cell membrane, releasing its contents, while lysate is the resulting cell contents released after lysis. Lysis refers to the process of breaking open cells, whereas a lysate is the mixture of cellular components released from the broken cells.
What is the difference between lysis and plasmolysis?
When a cell is placed in a hypotonic solution, water will enter the cell. This is called lysis. When a cell is placed in a hypertonic solution, water will leave the cell (causing it to shrink). This is called plasmolysis.
What is the scientific name for when cells swell and burst?
The scientific term for when cells swell and burst is "lysis". This can occur due to factors such as osmotic imbalance or physical damage to the cell membrane.
What does lysis solution do?
Lysis solution usually contains multiple components which will disrupt cellular membranes, inactivate proteins, and stabilize a nucleic acid component.

Why does the lysis mixture need to be incubated at 65 Celsius?
Incubating the lysis mixture at 65 Celsius helps to break down the bacterial cell membrane and release the genetic material, such as DNA or RNA, into the solution. This temperature is optimal for disrupting the cell membrane and denaturing proteins that could degrade the genetic material.
Why does the nattharick's solution not do the lysis of white blood cells?
The Nattharick's solution does not cause lysis of white blood cells because it is an isotonic solution, meaning it has the same osmotic pressure as the cells. This balance in osmotic pressure prevents the solution from causing the white blood cells to take up too much water or lose too much water, which would result in cell lysis.
What is lysis buffer?
A lysis buffer is a solution which is used to breakdown or separate the components of cells. Like all buffers, it is supposed to maintain the pH within a narrow range. Lysis buffers are used when analysis of separate components of the cell as desired - such as DNA isolation.
Role of RBC lysis solution in DNA isolation?
When isolating DNA from blood, white blood cells (WBC's) are the target. This is because RBC's do not contain a nucleus and therefore do not contain DNA. The function of the lysis buffer is to help in the lysis (or breaking) of white blood cells. WBC's must first be lysed so that the DNA may be released from inside the cell.
