PurposeDuring this experiment we compared the hemagglutinating activity reaction of control larn A solution at 2 mg/ml in defraud A buffer with the hemagglutinating activity reaction of your own purified Con A sample that you diluted previously at 2 mg/ml in Con A buffer. The purpose of this lab was to determine the strength of the reaction by performing serial dilutions on both the Con A sample and the control Con A sample, and determine through observations whether or non addition of galactose or mannose will inhibit this reaction. I hypothesize that the Con A + galactose solutions will demand fond(p) agglutination and partial no agglutination, and the Con A + mannose solutions will have all no agglutination.ResultsRows A and B had half agglutination and half no agglutination, while row C had all no agglutination. Row D had half agglutination and half partial agglutination, while row E had 4 columns with agglutination and 8 columns with no agglutination. Row F had complete a gglutination throughout.

This means that in the Con A + galactose solutions the ones that had agglutination the red cells aggregated with the lectin and sediment in the form of a uniform layer that covered the whole bottom of the well including the slopes, and in the Con A + mannose solutions the ones that failed to have agglutination take place covered only part of the bottom. We found through this experiment that the control Con A sample and the Con A sample had very similar strengths of reaction.ConclusionIn this experiment through serial dilutions on a 96 well plate we immovable the strength of the each reaction on both the Con A sample and the control sample. We found through our experiment that the addition of galactose or mannose will partially inhibit or inhibit the reaction between our Con A sample and control Con A sample.
