Comparison of peptide and protein identifications between peptides extracted by either solid phase extraction (SPE) or modified SPE (mSPE) methods. A total of 1066 unique urine peptides that originated from 305 unique human proteins were identified. Peptide extract from SPE and mSPE methods yielded (A) 195 and 912 unique peptides (B) from 61 and 283 unique proteins. Among the identified peptides 41 unique peptides from 31 unique proteins were commonly identified.
