what is the difference between trizol and trizol ls reagent?

TRIzol LS Reagent is similar to the original TRIzol Reagent in composition and results of use. TRIzol LS Reagent is designed for use with liquid samples such as blood and virus preparations in which large volumes of aqueous samples need to be processed, while TRIzol Reagent is designed for cell cultures or tissues.

Finally, PBW is more alkaline than Oxiclean, which is due to 30% of the formula being sodium metasilicate, a TSP alternative. ... It's active agent is sodium metasilicate, which is the same ingredient in PBW. Thankfully TSP/90 is cheap, and costs about the same per pound as oxiclean.

Triton is normally used in inmuno pp to isolate hydrophobic proteins; Tween 20 for lysis of cells and inmunoblots washes. The difference seems to be that Triton X-100 it has a phenolic ring that absorbs UV, can interfere in UV spectrometry to determinate proteins at 280 nm.

The TCLP is designed to determine the mobility of both organic and inorganic analytes present in liquid, solid and multi-phase wastes. ... For wastes containing greater than or equal to (≥) 0.5% solids, the liquid, if any, is separated from the solid phase and stored for later analysis.

i)Test Solution: These solutions are made from different reagents in an accurate measurements and other circumstances which is necessary for different chemical testings. ... ii) Volumetric solution: This type of solution is actually a homogeneous mixture of different solutes in a single solvent.

There is no difference, but propan-1-ol is the preferred name. In the "old" IUPAC system, the correct name was 1-propanol. But IUPAC now recommends that all locants (the numbers that locate a substituent or functional group on the chain) be as close as possible to the group they locate.

(D-L system labels the whole molecule, while R/S system labels the absolute configuration of each chirality center.) In short, the D-L system doesn't have direct connection to (+)/(-) notation. It only relates the stereochemistry of the compound with that of glyceraldehyde, but says nothing about its optical activity.

Both techniques are not alike in many respects, and the differences are glaring. Thin layer chromatography (TLC) is meant to separate the solids and some liquids. ... Gas-liquid chromatography, on the other hand, is intended to separate gases. This technique uses gas as its mobile phase and liquid as the stationary phase.

MLC doubles the amount of bits per cell, whereas TLC triples, and this opens up for higher capacity SSDs. ... MLC and TLC flash in comparison to SLC, is cheaper to produce, available in higher storage capacities, but at the tradeoff of relatively shorter life spans and slower read/write speeds.

Principle. The assay is based on the cleavage of the tetrazolium salt XTT in the presence of an electron-coupling reagent, producing a soluble formazan salt. This conversion only occurs in viable cells. Cells grown in a 96-well tissue culture plate are incubated with the XTT labeling mixture for 2 - 20 hours.

One major difference between the two methods is the light detector in absorbance spectroscopy is in line with the light path and the sample, whereas in fluorescence spectroscopy the light source and detector are at 90o to each other, with respect to the sample.

Down scaling and up scaling is possible with HPLC, micro HPLC is more sensitive, UHPLC is faster than TLC, pre and post column derivatization is possible with HPLC, different detectors can be used with HPLC, coupling with MS, MS/MS or NMR is possible with HPLC, results are more precise than with TLC.

While RFLP produces bands, uses restriction enzymes, uses radioactive probes to visualize, and uses southern blotting, PCR and STR don't. PCR and STR uses PCR amplification prior to running a sample while RFLP does not.

CHCl3 is a stronger acid among them. The acidic strengths of the other two alkyl halides be compared their inductive effects.

Laboratory methods. In the laboratory, acyl chlorides are generally prepared in the same manner as alkyl chlorides, by replacing the corresponding hydroxy substituents with chlorides. Thus, carboxylic acids are treated with thionyl chloride (SOCl2), phosphorus trichloride (PCl3), or phosphorus pentachloride (PCl5):

Re: Limiting Reactants & Limiting Reagents There is a subtle difference. A reactant is a directly reacting substance present at the initiation of the reaction whereas a reagent is a substance participating in a chemical reaction.
