How do you prepare 1 molar tris?
To make 1.00 litre of a 1.00 M Tris buffer you take 121.14 g Tris and dissolve it by adding water up to 1.00 L (the molar mass of Tris is 121.14 g/mol, that's why) There is a point where you need to set the pH so, its wise to dissolve the given amount in 700 ml ddH2O, setting the pH to 7.5-8.0 using Conc. HCl and then making up the final volume to a litre. filter with 0.5 micron filter and autoclave.
What ingredients are in the extraction buffer?
0.05M Tris-HCl (pH 8.0), 0.2% SDS, 5M Urea, and 1% 2- mercaptoethanol Aejaz Dar
How much of each ingredient do I need to make a 1mL lysis buffer solution?
You need to specify, lysis buffer for bacteria or eukaryotic cell. The most common buffer cocktail for eukaryotic cells is composed by an hypertonic solution and cell disrupters. To answer this question the proper amounts of the ingredients for 1 mL would be: 8.77 mg of NaCl (150 mM, the hypertonic component) 10 microliters NP-40 [can be replaced by 1 microliter (0.1%) of Triton X-100, a detergent] 6.06 mg of Tris in 100 microliters [Tris hydroxymethyl aminomethane, make 10 mL of a 100X solution (that is, 605.5 mg in 10 mL water, adjust to pH 8.0)] 890 microliters of distilled water. In some cases can be added some protease inhibitors such as PMSF, leupeptin, Aprotinin, etc. at concentrations of 1 microgram/mL. Store at 4oC for one month. Now, to make a lysis buffer for bacteria, the composition is different. For 1 mL mix: 6.06 mg of Tris in 100 microliters, as before 17.53 mg of NaCl (300 mM) 100 microliters of PMSF [Phenylmethylsulfonyl Fluoride, make 10X solution (1.742 mg in 10 mL of water)] 980 microliters of distilled water add aprotinin, leupeptin, and pepstatin at final concentration of 1 microgram/mL. Usually, to break the bacteria cell wall it is useful a lab blender. Disruption of both, eukaryotic and bacteria cells, must be done in cold conditions, usually on ice-water bath.
How do you make a 1 mol manganese dioxide solution?
Manganese dioxide is insoluble in water.
How many gram of water is equal to 2.2 mol of water?
2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol

How do you make 1X TE buffer?
10 mM Tris pH 7.5 and 1mM EDTA pH 8.0 For 1 L : 10 mL of 1M Tris-Cl pH 7.5 and 2 mL of 500mM EDTA pH 8.0
How do you prepare 0.1M tris HCl buffer of pH 8?
Tris(hydroxymethyl)aminomethane (Tris) has a molecular weight of 121.14 g/mol. 50 mM = 0.050 mol/L (x 121.14 g/mol) = 6.057 g/L To prepare a 1L solution first weigh out 6.057 g Tris Add roughly 70% of final volume of water (i.e. 700 mL) Use a pH-meter to measure the pH of the solution Lower the pH of the solution to 7.2 using undiluted HCl Use a measuring cylinder or volumetric flask to make the volume up to 1000 mL If you add too much HCl you need to add more Tris and then recalculate the amount of water that you need add. In this case, every 1 g of Tris requires 165 mL of water to be added.

Preparation of lysis buffer for genomic DNA isolation?
the following reagents and respective concentrations are for a total volume of 100ml lysis buffer. calculate the amount of these reagents required for the volume you need using N1:V1 = N2:V2 formula and finally make up the volume with sterile water. 0.2M tris HCl 0.5M NaCl 0.01M EDTA 1% SDS 1m sodium acetate
