Peptide Calibration Standard II

The Peptide Calibration Standard II is a commonly used calibration standard. It is a mix of well known physiologically relevant peptides.

It contains:

ACTH clip 1-17 17mer fragment of the glucocorticoid steroid production inducing hormone ACTH.
ACTH clip 18-39 21mer fragment of the glucocorticoid steroid production inducing hormone ACTH.
Angiotensin I 10mer precursor to Angiotensin II.
Angiotensin II A vasoconstricting and therefore blood pressure elevating 8mer.
Bombesin A 14mer peptide hormon that is also recognized as a marker for several malign tumors.
Bradykinin 1-7 A 9 amino acid long blood vessel dilating inflammatory mediator.
Substance P A neurotransmitter and neuromodulator made of 11 amino acids.
Somatostatin 28 A 28mer growth hormone-inhibiting hormone.
