What is content se- buffer in DNA extraction?
Tris pH 8.0 NaCl EDTA
Is there any difference between DNA and protein loading dye?
Yes, their components are different. Proteins loading dye besides bromophenol component for dying it has TRIS buffer, a reducing agent and SDS, which gives proteins a negative charge that lets them to migrate.
How do you prepare calcium buffer?
This might not be the best answer but, preparing a buffer solution allows one to keep the pH value the same when small amounts of acids or bases are added. Buffer solutions resist change in pH. Source: My Chemistry teacher's PowerPoint
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
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.
What is the difference between TAE buffer and TE buffer?
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.
What is Tris HCl?
"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.
What is the difference between tris tris cl and tris hcl?
tris tris cl is 6 cl and tris hcl is 3hcl...........

Role of tris in TE in DNA elution?
Tris is used as a buffering agent in the elution buffer.
What is tens buffer?
Tens buffer is made of: Tris: For maintaining pH EDTA: acts as chelating agent SDs: Detergent for denaturation of protein NaOH: Strong base, destabilises charge
What is the buffer capacity of Tris HCl?

What is the function of tris and EDTA buffer?

What is the difference between tris and tris hcl?
They are all basically the same thing. Tris-HCl is just the Tris base converted to a salt with HCl. You can buy either one. The advantage of starting with powdered Tris-HCl is that it is more soluble in water than the base and as a solution has a more neutral pH which is usually the desirable buffer point. Tris base has a pKa of over 8 so using Tris-HCl saves you the trouble of bringing it to a more neutral pH. The one thing to be careful of when making solutions from powder is to be sure to use the correct molecular weight which differs between the two. To answer your specific question, it doesn't matter which you start with except in the rare cases where the sodium from the NaOH would be an issue. For your situation where the solution is going to be slightly basic, it sounds like you could use either one as the starting reagent. I would go with whatever is already around the lab.
