D. Cell Culture
1. Recombinant Protein expressed in PLANTS containing No Animal-derived Components
Culture media without animal by-products have been attracting attention in tissue cultures for regenerative medicine and in the manufacturing
of vaccines or antibody drugs with cultured animal cells, etc.
In order to respond to these needs, Wako provides four kinds of recombinant proteins expressed in plants, namely bovine aprotinin, human lactoferrin, human lysozyme and bovine trypsin. Th ese products are free from contamination of viruses of human origin or BSE causative substances.

Aprotinin,
Bovine, recombinant, expressed in Plants, Solution
Th is product is used for the inactivation of trypsin by adding it after
trypsinization of adherent cultured animal cells.Protease inhibitory activity: > 5TIU/mg protein
1 TIU (Trypsin Inhibitor Unit)≒ 900 KIU (Kallikrein Inhibitor Unit)
8 UIP (Peptidases Inhibitor Units) = 1 KIU (Kallikrein Inhibitor Unit)
Lactoferrin,
Human, recombinant, expressed in Plants
This product is used suitably for the cultivation of general cells or
cells with low growth effi ciency, and for the production of IgG1
from hybridomas. IgG1 production from hybridomas in the
serum-free minimal medium is about 1.5 times higher than in the
transferrin-added media.
Protease inhibitory activity: > 5TIU/mg protein
1 TIU (Trypsin Inhibitor Unit)≒ 900 KIU (Kallikrein Inhibitor Unit)
8 UIP (Peptidases Inhibitor Units) = 1 KIU (Kallikrein Inhibitor Unit)
Lysozyme,
Human, recombinant, expressed in Plants
This product exhibits over 4 times higher bacteriolytic activity against
Gram positive and negative bacteria when compared to Lysozyme
from chicken egg white. The bacteriolytic activity is comparable with
Lysozyme of human origin. It is used optimally for the prevention of
contamination when producing recombinant proteins from animal
cells.Unit definition: One unit is defined as the amount of enzyme that will cause a change in absorbance of 0.001 at 450 nm using a suspension of Micrococcus bacteria as substrate.
Trypsin,
Bovine, recombinant, expressed in Corn
This product is used for the trypsinization of adherent cultured
animal cells.Activity: ≥ 72 TAME units/mg (≥ 3,300 USP units/mg)
Unit definition: One TAME unit is defi ned as the amount of enzyme that will catalyze the hydrolysis of 1 μmol Na-p-tosyl-Larginine methyl ester (TAME) per minute in the presence of 0.01mol/L calcium ion at 25 °C, pH 8.2.
1 TAME unit = 19.2 USP unit = 57.5 BAEE unit
