Molecular Weight (kDa):
Recombinant protein product has a calculated molecular mass of ∼60 kDa. Due to the abundant glycosylation, it migrates as approximately 80 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. See deglycosylation analysis image below.
SDS-PAGE Image
SDS-PAGE
Figure 1. Deglycosylation of purified recombinant proteins. Purified proteins were untreated (Lane 2) or treated with Protein Deglycosylation Kit under native (Lane 3) or reducing (Lane 4) conditions. Deglycosylation treatment resulted in a mobility shift of the protein to produce one major band at the expected size (∼60 kDa), thus indicating that the untreated recombinant protein (Lane 2, ∼80 kDa) was glycosylated.

Lane 2: Untreated protein (∼80 kDa, red arrow) under reducing conditions
Lane 3: Partially cleaved protein (∼60 kDa, green arrow) with deglycosylation enzymes under native conditions
Lane 4: Fully cleaved protein (∼60 kDa, green arrow) with deglycosylation enzymes under reducing conditions
