This Proteomics Grade Serum Tube (PGST) is developed specifically for collection of serum specimens. The tube contains five-protease inhibitors with specificity for the inhibition of serine, cysteine, aspartic proteases and aminopeptidases. PGST reagents instantly inactivate proteases thereby preventing changes in the proteome attributable to ex-vivo protease activity. All samples can be analyzed by mass spectrometry, SDS-PAGE, 2D-DIGE and Western blotting.

Benefits:

– Provides accurate, representative and reproducible results due to instant stabilization of serum proteins at the point-of-collection.
– Elimination of sample to sample variation and better confidence from knowing that the difference in protein abundance detected between samples is not due to ex-vivo protease activity
– Save time by eliminating the need to pre-mix or transfer serum from regular collection tubes
