    Structured Review

    Bio-Rad seldi proteinchip gold array
    (A) <t>SELDI</t> time-of-flight mass spectrum of unmodified rhTIMP-1 shows a molecular mass of 24,775 Da. (B) Mass spectrum of PEG 5K -TIMP-1 shows a molecular mass range of 46,529 Da –62,101 Da, indicating conjugation of 4–7 mPEG-5K chains; the most abundant species possesses 5 mPEG-5K chains. The smaller peaks in the range of 23,398–28,524 are consistent with doubly charged ions of the PEGylated species bearing 4–6 mPEG chains. (C) Mass spectrum of PEG 20K -TIMP-1 shows a molecular mass range of 45,139 Da –65,476 Da, indicating attachment of 1–2 mPEG-20K chains, with the mono-PEGylated species predominant. Doubly charged ions for the mono- and di-PEGylated species are also present, as is a peak for unmodified rhTIMP-1.
