Introduction
Legumain, also known as LGMN is a lysosomal cysteine protease which is found
in all mouse tissues, however it was mainly abundant in the kidney as well as
placenta. LGMN plays an essential role in the endosomal/lysosomal degradation
system as the Legumain deficiency causes the accumulation of pro cathepsins B, H
& L, another group of lysosomal cysteine proteases. Furthermore, over
expression of LGMN in tumors is important for invasion/metastasis.
Description
LGMN produced in Sf9 Baculovirus cells is a single,
glycosylated polypeptide chain containing 426 amino acids (18-435a.a.) and
having a molecular mass of 48.6kDa.
(Molecular size on SDS-PAGE will appear at
approximately 40-57kDa).
LGMN is expressed with an 8 amino acid His tag at
C-Terminus and purified by proprietary chromatographic techniques.
Source
Sf9,
Baculovirus cells.
Physical Appearance
Sterile filtered colorless solution.
Formulation
LGMN protein solution (0.5mg/ml) contains Phosphate
Buffered Saline (pH 7.4) and 10% glycerol.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
