How do you make up 75mM Tris HCL buffer solution?
CONVERT TO THE MOLE (0.075 m/l) * (157.67mw) =11.82 g/l
Two components that make up a buffer include?
A buffer is made up of an acid and its conjugate base.
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
Which has higher density salt water or fresh?
Salt water has a higher density than fresh water. Fresh water is only made up of two things, hydrogen and oxygen. Salt water is made up of hydrogen oxygen sodium and chlorine, which gives it a higher density.
Why is a sodium phosphate buffer used for the pH 6.24 buffer?
Phosphate ions are used as a buffer because there are three protonated forms (H3PO4, H2PO4-, and HPO42-) that have pKa in the correct range. The pKa for the three listed forms of phosphate are 2, 7 and 12 respectively.See the Related Questions and Web Links for more information.

Function of TES buffer?
1. TES buffer - zwitterionic buffer that is used in biochemistry and molecular biology research. It is one of the Good buffers developed in the 1960's to provide buffers in the pH range of 6.15 - 8.35 for wide applicability to biochemical studies. 2. TES buffer is a solution made up of Tris, EDTA and NaCl. Its primary purpose to reduce the acidity of a solution. It is pH stable and is also isotonic. 3. TES buffer - made up of Trizma acetate [FW=181.19], EDTA and Sucrose. Same function as described in 2.

Role of extraction buffer in DNA isolation?
TE buffer contains EDTA, which is a strong chelating agent. It chelates the Mg2+ ions present in the solution. Since endonucleases use Mg2+ for their activity, degradation is slowed or checked using this buffer. This buffer is also maintained at a pH of 8.0 for the same reason. At this pH, the endonucleases show least activity. All in all, the DNA or RNA sample that we have is safe from getting degraded.
Action of TENS buffer in isolation of plasmid DNA?
TENS buffer is made up of: Tris, EDTA, NaOH, and SDS.Tris: buffer solution usually used for nucleic acids, makes sure that the pH stays fairly constant throughout procedureEDTA: chelating agent, chelates positively charged ions like Mg2+ and Ca2+ that might harm the DNANaOH and SDS: disrupts cell membrane so you can get the DNA out
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.
Why is the phosphate buffer made up by using the Henderson hasselbalch equation not the expected PH?

Who does Tobias end up with in Divergent?
Tris loves her Dauntlessinstructor Tobias (Four) in Divergent.
What is the recipe for Lysis buffer?
Bacterial lysis buffer: 1mL 1M Tris-HCl pH 8.0 200uL 0.5M EDTA 15g sucrose (add to water, not the other way around) 200mg lysozyme 20mg pancreatic RNase 10mg BSA Bring up to 100mL with water filter sterilize (do not autoclave)
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.

Are swamps made up of salt water or fresh water?
Swamps are made of both.
