Tris, or tris(hydroxymethyl)aminomethane, or known during medical use as tromethamine or THAM, is an organic compound with the formula (HOCH 2) 3 CNH 2. It is extensively used in biochemistry and molecular biology as a component of buffer solutions [2] such as in TAE and TBE buffers, especially for solutions of nucleic acids.

May 24, 2019 · Tris buffer helps maintain a stable pH, which is important for medical and lab processes. Tris buffer is used in DNA extraction and other chemical analyses due to its pH stability. You can easily make Tris buffer by dissolving it in water and adjusting pH with HCl.

TE buffer is a commonly used buffer solution in molecular biology, especially in procedures involving DNA, cDNA or RNA. "TE" is derived from its components: Tris, a common pH buffer, and EDTA, a molecule that chelates cations like Mg 2+. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.

This buffer calculator provides an easy-to-use tool to calculate buffer molarity and prepare buffer solutions using the formula weight of the reagent and your desired volume (L, mL, or µL) and concentration (M, mM, or nM).

Sep 26, 2023 · There are two methods to prepare a Tris buffer solution. One method is to prepare solutions of Tris base and Tris HCl at the necessary concentrations, then add aliquots of one solution (typically Tris HCl) to the alternative (typically Tris base) solution while monitoring the pH until the proper pH is attained. In actuality, this is quite unusual.

Tris is a chemical with basic properties, having a pKa of 8.1. It can be used to buffer solutions from drastic pH changes, keeping them in the pH range of 7.0 to 9.0. Determine the mass of Tris base to weigh by multiplying the number of moles by the molecular weight (121.14 g/mol) of Tris.

10 mM Tris, 150 mM Sodium Chloride, 0.1% Sodium Azide, pH 8.0 ± 0.1 This buffer is designed for use with Recombinant Apoferritin. It is also a suitable Tris buffer for use when additional buffer salts are needed.

Tris is one of the most frequently used buffers in cell and molecular biology experiments. It has a pKa value of 8.06 at 25°C and an effective pH range between 7.0 and 9.0, which perfectly corresponds to the physiological pH range.

Tris buffered saline (TBS) is isotonic and non-toxic. TBS provide optimal conditions for antigen – antibody interactions. TBS composed of Tris and NaCl. While the former component gives the buffering capability, the later one helps in tonicity.
