Sperm Enzyme Preparation (Group 6)
Comparing all Gradient Gel Standards
Experiment Objective
Compare all given gradient gel standards and use their relative mobilities to create the
best fit mathematical model.Use best model to compare two gel samples
Gathering Data:
Gels 1 and 2
Hypothesis (Part One)
Standards will be reproducible.
Hypothesis (Part Two)
Has more proteins than
Standards
Measured three timesCalculated relative mobilitiesCalculated mean measurementsBest fit mathematical model

The Reaction
The expansion of the Vitelline Envelope due to contact with sperm over a 30 minute time period.
Comparing Unknowns to Standards
Vitelline Envelope control Sperm enzyme control Vitelline Envelope + sperm enzyme (t=0 min) Vitelline Envelope + enzyme (t=5 min) Vitelline Envelope + enzyme (t=10 min) Vitelline Envelope + enzyme (t=15 min) Vitelline Envelope + enzyme (t=30 min)
Results:
Sperm enzyme controls between gels 1 and 2 were similar.
