Most suitable for initial exploratory analyses. Available only for small QconCATs (<50 kDa),

 

Delivered in denaturing buffer.

Product box

QconCAT - Superior

Product Code: PQ-HQ-1

Custom-made QconCAT

purified protein

dialysed to appropriate storage buffer

absolutely quantified

 

Available as unlabeled protein or as heavy isotope-labeled protein (e.g. 15N, 13C Arg/Lys, 13C, 15N Arg/Lys).

 

Recommended for routine and high throughput analyses.

 

Delivered in individually determined storage buffer.

Each QconCAT is quality controlled via SDS-PAGE (purity) and LC-MS/MS (identity, labelling efficiency, quantity).

Delivery costs depend on destination and packaging. Bioinformatic support for data analysis is available upon request.

Absolute protein quantification made easy

QconCATs (Quantification conCATamer) are custom-made synthetic proteins, usually comprising of up to 50 heavy isotope-labelled proteotypic peptides, functioning as true internal standards for protein quantification using mass spectrometry.

Save time and resources

Skip time-consuming preparation of peptide mixes and spike your analyte sample with up to 50 reference peptides in a single pipetting step.

Simplify large-scale analyses

Quantify whole proteomes in a single experiment using several QconCATs

Individually produced

Receive custom-made isotope-labelled QconCAT proteins, based on a detailed analysis of your requirements

Scalable

Production of large amounts of QconCAT for high throughput analyses

Robust

Compare data between laboratories and instruments

Internal control

Minimize sample preparation bias by early addition of the internal standard

Support

Our experienced team provides support from selection of proteotypic peptides to setting up your targeted method in Skyline.
