Description

ACTH Fragment Set (1-17 + 18-39) — MALDI-TOF Standards, 0.5 mg each — research overview

A two-vial set of ACTH fragments (residues 1-17 and 18-39) supplied as MALDI-TOF mass calibration standards in the 2000–2500 Da range. These are the most widely cited mid-mass MALDI calibrants in published proteomics workflows.

Peptide Shop supplies ACTH (1-17) + (18-39) MALDI calibration set (2 × 0.5 mg vials (one of each fragment)) as a sealed research material with lot-level documentation. This product is supplied for in-vitro laboratory research only and is not intended for human use, veterinary use, therapy, diagnosis, cosmetic application or consumption.

Research applications

  • MALDI-TOF mass calibration in the 2000–2500 Da range
  • Reflectron-mode mass-accuracy verification
  • Daily MALDI system-suitability QC
  • Component of larger MALDI calibration mixtures (with insulin, ubiquitin etc.)

Sequence and analytical data

Each fragment supplied at ≥98% HPLC. [M+H]+ values: ACTH (1-17) = 2094.4, ACTH (18-39) = 2466.2. Identity confirmed by MALDI-TOF.

Storage and handling

Store lyophilised at -20 °C. Reconstitute in 50% acetonitrile / 0.1% TFA at 1 pmol/µL for MALDI spotting.

Documentation

A lot-specific Certificate of Analysis is available in EN, DE, FR and ES from the product detail page after dispatch. The CoA reports HPLC purity, identity confirmation, appearance, and storage and handling guidance for the dispatched lot.

FAQs

Why a two-fragment set?

The combination of ACTH (1-17) and (18-39) provides two well-separated calibration points in the mid-mass MALDI range, improving polynomial mass-calibration accuracy across 2000–2500 Da.

Are these compatible with standard MALDI calibration mixtures?

Yes — they are routinely combined with bradykinin (1-7), Angiotensin I, insulin oxidised B-chain and bovine ubiquitin for full-range MALDI calibration.

Recommended matrix?

α-CHCA in 50% acetonitrile / 0.1% TFA is standard for both fragments.
