This product is a mixture of 22 peptides derived from the post-trypsin digest of QCAL. This is a lyophilized powder. Upon reconstitution with an appropriate solvent - typically 0.1% formic or trifluoroacetic acid in water - the solution is injection-ready.

General description
QCAL was designed using the QconCAT technology and recombinantly expressed in E. coli. The parent protein sequence of QCAL is as follows:

QCAL was subsequently digested with trypsin to give a core mixture of 22 peptides.
