Cysteine

Cysteine; Cys

Functioning at the core of various biological processes, cysteine (Cys) is a key subject of biochemical analysis. Its concentration levels are highly indicative of the functional state and metabolic vigor of the sample. In addition, thus, accurate determination using this assay supports advanced exploration in biochemistry and molecular biology.

Designed for comprehensive functional analysis of cysteine (Cys) within tissue metabolism profiling, coenzyme utilization studies, and biochemical pathway modeling.

Superior Accuracy; Low Background Noise; Highly Stable Signal Output

1. Pre-Centrifugation of Vials: Prior to opening any reagent vials, perform a brief centrifugation to collect all powder or liquids at the bottom of the tubes.

2. Reagent Equilibration & Mixing: Allow all kit reagents and buffers to equilibrate to room temperature (25 °C) before initiating the assay.

3. Sample Storage: If samples are not assayed immediately, please store at -80 °C and avoid repeated freeze-thaw cycles.
