  • However, this observation has not been confirmed in three subsequent studies, which instead have suggested that the original immunoblot finding resulted from nonspecific cross-reaction either with contaminating bacterial proteins (18) or urinary IgG fragments (19, 20).

Examples

  • GTU-54-oAI was compared antigenically with other species of human mycoplasmas using an immunoblot method as described previously.

  • The researchers used an immunoblot to identify the specific proteins in the blood samples.

  • After performing an immunoblot, they found that the protein markers were present in all tested subjects.

Surface Forms

immunoblot singular
immunoblots plural

Morphology

immunoblot = blot (semi-transparent) = immuno + blot

Formed by the combining form 'immuno-' + 'blot'; the structure is clear in technical contexts but 'immuno-' is a specialist combining form not familiar to average B1 learners.

Etymology

Immunoblot comes from immuno- meaning 'related to the body's defense' and blot meaning 'a mark or stain', like using ink to show a target. So an immunoblot is a lab technique that uses parts of the immune system called 'antibodies' to mark and find specific proteins in a sample.
