Synthetic (linear) peptides (Ac-CTEDRIQHALER-NH2 and Ac-CYKPEKSDLSSPNH2) corresponding to aa8-19 and aa838-849, respectively, of human PI3 kinase p101. Each peptide has an acetyl group blocking the amino terminus and an amide group blocking the carboxyl terminus. Theoretical Molecular Weight ((M+H+): Ac-CTEDRIQHALER-NH2: 1407.77 D Ac-CYKPEKSDLSSP-NH2: 1353.65 D Applications: Suitable for use in Western Blot. Other applications not tested. Storage and Stability: Lyophilized powder may be stored at 4C for short-term only. Stable for 12 months at -20C. Reconstitute to nominal volume (see reconstitution instructions for peptides) and store at -20C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer.
