When you ran this protein directly on reversed phase-HPLC with UV monitor set at 280 nm, two peaks were resolved. Mass spec determined that the peaks represented Chain A and Chain B, respectively. The peak area is 500,000 for Peak A (Chain A) and 100,000 for Peak B (Chain B). The molecular masses of Chain A and Chain B are 25,000 and 5000, respectively.
