Build your multi-analyte detection panel. Use the Analyte Builder to add each individual target. Select multiple matrices and species — add your own custom values with Other.
Panel Identity
Describe the biological focus. Individual analytes are added below using the builder.
Assay Platform
Platform determines the upper limit of analyte count and instrument requirements.
Panel Configuration
Analyte List Builder
Add each analyte with its reporting unit. Every row is one target. Add as many as your panel requires.
Analyte List0 added
Sample Matrix
Select all matrices. Each requires separate spike-recovery validation.
Species
Select all species. Add custom species with Other.
Design your custom peptide or sequence: synthesis route, N- and C-terminal modifications, side chain chemistry, purity grade and scale. Paste your sequence in single-letter IUPAC code for live residue count, MW estimation and validation.
Peptide Identity
Include protein of origin if derived from a known sequence.
Synthesis Route
SPPS-Fmoc is standard for most peptides under 50 residues.
N-terminal Modification
Select one. Leave as Free N-terminus if no N-terminal modification required.
C-terminal Modification
Select one. Leave as Free acid if no C-terminal modification required.
Side Chain / Internal Modifications
Select all that apply. Specify residue positions in the notes section below.
Purity Grade & Scale
Determined by RP-HPLC.
Amino Acid Sequence Input
Single-letter IUPAC code only. Spaces and line breaks are automatically ignored. Live statistics appear below the input.
