IMSLECP1

Molecular weight over 10,000 Daltons; almost always protein in nature

portion recognized as foreign, reacts specifically with an antibody receptor

with 2 parts carrier and haptene

either carrier or haptene

antigens that belong to the host

from the same species and capable of eliciting an immune response

are from other species, such as other animals, plants or microorganisms.

are heterogens that exist in unrelated plants or animals but are either identical or closely related in structure so that antibody to one will cross=react with antigen of the other
