Once the lizards reached adulthoodaAC"approximately 1-year-oldaAC"the scientists assessed the animalsaACAO immune function by measuring the ability of their blood plasma to hold a foreign protein
Concerns about enzymes include the fact that they are proteins and can, in a limited number of cases, cause an immune response in humans, as any foreign protein
will; however, it is rare to see an allergic response or sensitization to enzymes.
Currently, with increasing concern regarding the nutrition and flavor of food products, the development of wheat-based bakery foods that are enriched with foreign protein
additives is increasingly popular .
KDEL, endoplasmic reticulum (ER) retention signal, was used to enhance foreign protein
accumulation in ER.
Upon recognition of such foreign protein
fragments, T cells kill the aberrant cells.
This affinity matrix was selected due to the isolation of targeted molecule from the abudance of foreign protein
which can be purified using high recovery and fold in single step through a specific binding of ChE bound to the matrix and selectively removed under elution phase by the increase of ionic strength using high salt concentration.
Most serologic tests aim to detect antibodies produced from the body's response to an antigen or foreign protein
of an infectious organism.
In most cases the transgene failed to produce desired quantity of foreign protein
in the heterologous system (Haseloff et al.
"Looking for some small foreign protein
in that very complicated background is not easy."
production in plant tissue cultures; Curr Opin Biotechnol 1999; 11: 199-204.
An allergic reaction is caused by an overreaction of the body's immune system to a foreign protein
(an allergen) that is either inhaled, eaten, touched or injected.
Commercially available sutures made from natural proteins such as silk and catgut are absorbable by the body but often trigger inflammation due to their foreign protein
structure that differs from what the body itself produces.
