Cells were cultured at 33°C (33), 39°C for 2 days (39), or 2 days at 39°C followed by an incubation at 33°C for 1 (experiments 1 and 2) or 2 days (experiment 3) (39-33).
Values shown correspond to the amount of joining products relative to the amount for control actin. The intensity of hybridizing bands was quantitated with a PhosphorImager.
The ratio is derived by dividing the value for an IJ with the value for an CJ. For example, 0.36 is the ratio of 0.89 (VλVκ) to 2.5 (VλJλ).
—, both CJ and IJ values are too small to be significant for ratio calculation.
The quantitation is derived from Fig. 2B. Values are average intensities of the PCR products ± standard error on two different dilutions for each DNA sample (i.e., undiluted and threefold-diluted DNA).
