Effect of temperature on wrwycr uptake by J774A.1 cells

Temp (°C)	Result for the indicated input total wrwycr concn at the following time of incubationa:
	5 h						24 h
	50 μM		100 μM		150 μM		50 μM		100 μM		150 μM

^aThe total peptide concentration is expressed by using the molecular mass of the peptide monomer rather than that of the peptide dimer. D, peptide dimer; M, peptide monomer.

^b[Pep], measured intracellular peptide concentration (mM).

^cThis concentration of peptide is unusually lower than the average for the same treatments described in Table 1.
