Tris(hydroxymethyl)aminomethane (Tris) is a common buffer used in biochemistry, while Tris HCl is Tris buffer combined with hydrochloric acid to adjust the pH. Tris buffer is neutral (pH 7-9), while Tris HCl is acidic with a pH around 4.5-8.6.
The buffer capacity of Tris HCl depends on its concentration and the pH range of interest. Typically, Tris HCl has a good buffering capacity around its pKa value of approximately 8.1. At this pH, Tris HCl can resist changes in pH when small amounts of acid or base are added.
"Tris" is a chemical compound used as a buffer. The full name is tris(hydroxymethyl)aminomethane. Tris has the ability to absorb counter ions (+H and -OH) so as to help keep the solution that they are in at a stable pH level. When the pH of Tris is set using HCl (hydrochloric acid) the buffer is called Tris HCl.
To make a Tris buffer at pH 7.5, you will need to mix Tris base with HCl. To calculate the volume of 5M HCl needed, you will first need to determine the molarity of the Tris buffer solution and then use the Henderson-Hasselbalch equation. The exact volume of 5M HCl required will depend on the amount of Tris base used and the final volume of the buffer solution.

The main difference is in composition. In TE common Tris buffer is bring down to pH 8 with HCl and EDTA is involved but in TAE instead of Tris HCl in TE Tris-acetate buffer is used.

Tris HCl is used as a buffer in DNA isolation to maintain a stable pH level during the process. It helps to prevent pH fluctuations that can affect the integrity of the DNA molecule. Tris HCl also aids in the solubilization of proteins and DNA, ensuring efficient extraction of DNA from the sample.
Tris-HCl and NaN3 are commonly found in TD buffer. Tris-HCl helps maintain a stable pH, while NaN3 serves as a preservative to prevent bacterial growth.

To make a 1 mol tris buffer, you would need to dissolve 121.1 g of Tris (Tris(hydroxymethyl)aminomethane) in water and dilute to a final volume of 1 liter. Adjust the pH with a strong acid like HCl or a strong base like NaOH to reach the desired pH of the buffer.
Tris HCl is used in plasmid isolation procedures to maintain a stable pH in the lysis buffer, which is crucial for DNA stability and efficient binding of the DNA to the purification matrix or column. Tris HCl also helps in denaturing proteins and disrupting cell membranes during the lysis step, facilitating DNA release.
Tris buffer can resist changes in pH because it is a weak base and its conjugate acid can soak up any added H+ ions (from HCl). Sodium acetate, on the other hand, does not resist changes in pH as effectively because acetate is a weak base and not able to counteract the addition of H+ ions as efficiently as the conjugate acid of Tris buffer can.
Tris refers to tris(hydroxymethyl)aminomethane, which is a buffer commonly used in biochemical and molecular biology experiments. Tris HCl, on the other hand, is tris that has been neutralized with hydrochloric acid, resulting in a salt form commonly used in biological and biochemical applications. The main difference is that tris HCl already contains chloride ions, while tris alone does not.
