Netrin-1 Peptide Is a Chemorepellent in Tetrahymena thermophila

Figure 1

Netrin-1 peptide is a chemorepellent in Tetrahymena thermophila. The EC₁₀₀ of this peptide is 1 μM. The EC₅₀ of this peptide is approximately 1 nM. “Cells Showing Avoidance” represents the mean of at least 6 trials, and error bars represent the standard deviation. Each trial consisted of 10 cells which were individually observed and scored for avoidance within the first 5 seconds of exposure to netrin-1 peptide.
