  1. Direct ELISA of Alpha-Amylase Ellyn Daugherty SM Biotech Career Pathway www.BiotechEd.com ellyn@BiotechEd.comwww.sargentwelch.com/biotech www.emcp.com/biotech • Welcome to my workshop: • Fill in the card in the tri-fold brochure(if I don’t already have one from you) and turn it in to me a copy of my curriculum. • Please read through these slides (on the handout in your pee-chee folder). • When done, please read through the lab packet (in the pee-chee folder). :-) Ellyn

  2. In Biotech, companies find a product of interest (amylase) and make sure to have assays to show it’s presence, activity, & concentration • Amylase is an enzyme that catalyzes starch digestion. • It is used commercially in several ways including: • Remove starch in products • Produce sugar from starch • Processing of cellulostic biofuel

  3. The rAmylase Project is the focus of the 2nd semester of the SMBCP • Learn how to assay for a protein of commercial interest (amylase) • Transform cells to produce that protein (using pAmylase and C2523 cells) • Scale-up cells to volumes where amylase can be purified and assayed

  6. Introduction toELISA ELISA– short for enzyme-linked immunosorbant assay An ELISA uses antibodies with conjugated enzymes to specifically identify and measure the amount (concentration) of a protein in a solution

  7. ELISA • A specific antibody (Ab) recognizes a specific protein (Ag). • An enzyme bound to the Ab causes a color change in a substrate (so you can “see” the Ab is there). • The more color in a well, the more Ab-enz complex is bound to target protein = higher target protein concentration.
