13C cuaternary centers in amino acids

I've got a sample of about 5mg of an amino acid that is the final product of a a synthesis. Due to the long relaxation time that the carboxilic and the alpha C we only got a 200 varian Mercury instrument and we're unable to obtain those signals. I was wondering if an APT is better than DEPT, because we're only interested in this signals and i've heart the overall pulse sequence is shorter than the DEPT, increasing the number of scans in the same period of time
