The PI of protein is 9.24 At what PH MY protein binds to the column and which type of column have to use for purifification?
To purify a protein, you typically use a column with a pH slightly above the protein's pI. Since the protein has a pI of 9.24, you would likely use a column with a pH around 9.5-10 for purification. The specific type of column to use would depend on the properties of the protein and the purification method you are employing (e.g., ion exchange chromatography, affinity chromatography).

What is 20 column volume?
In the context of chromatography or column-based purification techniques, a "20 column volume" refers to a volume of solvent or eluent that is equivalent to 20 times the volume of the column's packing material. This measurement is often used to determine the amount of solvent needed for flushing, equilibrating, or eluting compounds from the column. For example, if a column has a volume of 10 mL, a 20 column volume would be 200 mL of solvent. This ensures thorough cleaning or elution of substances within the column.
If a protein with pi of 6 is purified on a DEAE column is it better to use pH 4ph 6 of pH 8 why?
DEAE columns contain a positively charged resin to which negatively charged molecules and proteins will bind. In protein purification, one will generally have the target protein bind the column so the non-target proteins will "flow through" after which the bound proteins are "washed off" the column by changing either the pH or salt concentration. Since the pI of the protein is 6.0, at pH=6.0, the protein has a net charge of zero and will not bind the column, so this pH is not suggested. When the pH is greater than the pI, the protein has a positive charge, so at pH=8.0 the protein will be repulsed by the positively charged resin and will not bind, so pH=8.0 is also not recommended. When the pH is less than the pI, the protein carries a negative charge and will bind the DEAE column and can thus be purified, so the pH=4.0 condition will be productive toward protein purification for this protein.
How do you separate the enzymes in column chromatography?
In column chromatography, the enzymes are made to pass through the column without occurrence of bubbles. These enzymes are obtained at the end of the process by slowly advancing through every column.

How do you know if it is a load bearing wall?
A wall without column structure. The wall itself support the loading from the upper floor. In conventional structure, the column support the loading from the upper beam and transfer it to the lower beam.
When inserting a column if you select column D where will the new column be inserted?
The inserted column will push column D to the right and become the new column D. The original column D will become column E, and so forth.
Why do you condition a column in Solid Phase Extraction?
When functionalized silica sorbent is dry, the functional groups are laying flat against the surface of the silica. Conditioning, or "wetting" the sorbent, allows the functional groups to float free of the silica surface, increasing their surface area and effectiveness.
How is silica gel column chromatography used in the separation and purification of compounds?
Silica gel column chromatography is a technique used to separate and purify compounds based on their different affinities for the silica gel. The mixture of compounds is loaded onto a column filled with silica gel, and as the solvent flows through the column, the compounds move at different rates based on their interactions with the silica gel. This results in the compounds separating into distinct bands, allowing for their isolation and purification.
When you insert a column where does it automatically go?
The column will go where the currently selected column is, pushing all columns to the right. So if column D was selected and you inserted a column, column D would become column E and the inserted column would now be column D.The column will go where the currently selected column is, pushing all columns to the right.

What is difference between column and pillar?
In many cases these terms are interchangeable, but a column is usually subjected to mainly axial vertical loading, with some lateral load/moments, whilst a pillar is usually subjected mainly lateral loading (as a cantilever), with some axial vertical loading- an example of a pillar is to support retaining walls, or on the outsides of old buildings like cathedrals.
How does the elution buffer work in the process of protein purification?
The elution buffer helps to release the purified protein from the column by changing its chemical environment, causing the protein to detach and flow out of the column for collection.
What is the vertical section of the ocean from the surface to the ocean floor referred to as?
This section of the ocean from floor to surface is called the water column.
What is loading point in packed column?
The point in which the droplets of liquid (solvent) are carried up with the gas in packed column. This hapens if the solvent flow is fixed & the gas flow is icreased.
