Reagent

reagent --> periodic acid Schiff reaction

(Science: technique) A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping.

It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product.

The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour.

Acronym: PAS

Re:

it doesn't have to be only the buffer but any additive you're using other additive that I used is antimicrobial reagent-tetracycline HCL which is I used for prevent any contamination in the reaction but I think there is no difference after added this reagent, means that OD blank ...

Simulated intracellular fluid

It is difficult to simulate intracellular fluid by using chemical reagent. Another way is using NP40 or OG to lysate the cell and collect the cell lysate. Then spin down the proteins and get the intracellular fluid. Will ___________________________________________________________________________________________ ...

Protein isolation

... not grown as 2D monolayers (I am looking at cell aggregates to be specific). Our original plan is to isolate the protein using trizol extraction reagent, then run an ELISA on HIF 1 alpha. However, I am worried that the protocol may not work. I haven't heard of trizol being used for a specific ...
