noun, plural: conjugations


(1) The process whereby two ciliates come together in a temporary fusion to exchange micronuclear material, then separate, each being a fertilized cell.

(2) A form of sexual reproduction in certain algae and fungi where a male gamete unites with a female gamete resulting in the union of their nuclei and the subsequent formation of a zygote.

(3) The temporary joining together of two bacterial cells to transfer genetic material via the plasmid (either as solitary or as part of a chromosome) from the donor cell to the recipient cell.


(1) The joining together of two compounds resulting in the formation of another compound, such as the conjugation of a toxic compound with another compound in the body to detoxify and eliminate it.

(2) A system of delocalized orbitals consisting of alternating single bonds and multiple bonds.

(general) The act or state of joining together; union; conjunction.


Bacterial conjugation is a beneficial process in bacteria since they can acquire a gene that confers survival or a novel characteristic which enables them to thrive in harmful conditions or to utilize a new metabolite. It is through this process that resistance to antibiotics can be transferred from one bacterial cell to another.

Word origin: From Latin coniugātiō (“‘combining, connecting; conjugation’”), from coniugō (“‘join, unite together’”), from con- (“‘with’”) + iugō (“‘join, bind, connect’”).

Re: Lateral Flow Assay

... long? A friend did IgE aptamer that was under 50 NT and got it to work (she used FITC with her antibodies though). Hopefully you are assessing the conjugation before you start the assay. Can you check how the tethering went?
