In addition of being tedious and lengthy, the process of batch digestion of proteinaceous species is also froth with the contamination of enzymes auto digests.
It is well understood that as the digestion proceeds in batch, the auto-digested enzymes no longer have a similar behavior as the intact enzymes.
Moreover, batch digestion is an anachronistic process that should no longer remain in the lexicon of today’s concept of real-time modus operandi.
To highlight the point, we have plotted the previously digested Trypsin on the immobilized Trypsin reactor, along with the digests of Cytochrome c from equine using similar conditions in both cases.
See Application Note 144:
How would a Trypsin solution behave and how would it affect the immobilized Trypsin on the column.
We have, in this application note, look at this issue.
See Application Note 142:
If we were to add the Tryspsin solution in excess, would that digest the immobilized Trypsin?
This Application Note clarifies this question.
See Application Note 153:
Automated Digestion of Trypsin with StyrosZyme® TPCK-Trypsin, Immobilized Enzyme on Polymeric Hard Gel Simulated-Monolith™ Enzyme Reactor with the Acquity UPLC I class Plus and Final Silica mapping. Result of excess injection of Trypsin on the Trypsin column.
Heartcutting is commonly used to specifically remove components from a mixture without resorting to affinity columns or the like.
It is however promoted as a somewhat involved process.
We are offering a simple alternative here:
See Application Note 147:
Alternatively using a different instrument with the same 6 port valve it is possible to show the process is universal.
See Application Note 148:
Identifying small amounts of chemicals in large volumes has been a time consuming and resource wasting process that is cluttering the relevant industries for some time.
Solid phase extraction coupled with high performance polymerics on the same column is the proper alternative.
