Eva Engvall

[2] Her postdoctoral work was done at the University of Helsinki and City of Hope National Medical Center in California, where she was subsequently appointed to staff.

From 1993 to 1996, Engvall held joint appointments at Sanford-Burnham Medical Research Institute and as Chairperson of the Department of Developmental Biology at Stockholm University.

Eva Engvall was one of the two Swedish scientists at Stockholm University (the other was the principal investigator Peter Perlmann) who conceptualized and developed the ELISA technique.

She discovered the affinity of fibronectin to gelatin (denatured collagen),[11] demonstrating the potential of these two matrix components to form a complex in tissues.

[12][13][14][15] Perlmann and Engvall were honored for their invention when they received the German scientific award of the "Biochemische Analytik" in 1976, 5 years after they had published their first papers.
