Protein Reaction Mix

This protocol describes how to perform absolute quantification assays of target proteins within complex biological samples using selected reaction monitoring. It was used to accurately quantify proteins of the mouse macrophage chemotaxis signaling pathway. Target peptide selection, assay development, and qualitative and quantitative assays are described in detail.

Polystyrene is a good insulator, so you can assume that no heat is exchanged between the inside and outside of the cups. The calorimeter itself will absorb some heat, which you'll account...

In a precipitation reaction, aqueous solutions of soluble salts react to give an insoluble ionic compound – the precipitate. The reaction occurs when oppositely charged ions in solution overcome their attraction for water and bind to each other, forming a precipitate that separates out from the solution. Since such reactions involve the exchange of ions between ionic compounds in aqueous solution, they are also referred to as double displacement, double replacement, exchange reactions, or...

In game theory, mixed strategies involve players choosing their actions randomly from a set of available options. This approach contrasts with pure strategies, where players select a specific action with certainty. Mixed strategies become relevant in scenarios where there is no pure strategy equilibrium. A mixed-strategies Nash equilibrium occurs when players adopt strategies so that no one can benefit by unilaterally changing their own strategy, given the strategies of the others. In this...

Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation indicates the reacting species and the product species, but it reveals no details about how the reaction occurs at the molecular level. The reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs. For instance, the decomposition of ozone appears to follow a mechanism with two steps:
