For a company that sells ELISA kits. Elisa kits are used by researchers/scientists to detect,for example, proteins by imonological assays and are capable to tell the level of proteins present in a sample.
For that reason the logo represents the shape of an antibody (that is the foundation of the methodology - an imunological technique). And it is also represented the levels of protein measured.
It's a sort of abstract iconic logo that represents the antibodies and the levels of proteins that they can measure.
