The phrase "an initial cycle" is correct and usable in written English.
It can be used to refer to the first occurrence or phase of a repetitive process or series of events.
Example: "During the initial cycle of the experiment, we observed significant changes in the data."
Alternatives: "a preliminary cycle" or "the first cycle".
Thermal cycling conditions consisted of an initial cycle at 95 °C for 10 min, followed by 40 cycles each of 15 s 95 °C and 1 min 60 °C.
Cycling conditions for genotypings comprised an initial cycle at 60°C for 1 min and 95°C for 10 min, followed by 55 cycles at 92°C for 15 s and 60°C for 1 min, and a final step at 60°C for 1 min. The fluorescence intensity of was measured by the 7500 RT-PCR System (Applied Biosystems).
The thermal cycling parameters were as follows: an initial cycle of Taq activation for 1 min at 94°C, 1 min at 55°C, and 1 min at 72°C and optimized annealing temperature 5 sec at 58 60°C, 30 sec at 72°C, and a detection step of 8 sec at 80°C.
After an initial cycle at 94°C for 1 min, reactions were cycled 30 times (94°C for 30 s; 68°C for 3 min) in a thermocycler (BioRad, Hercules, USA).
To detect AFLP fragments, Eco primers were labelled using a fluorescent dye (FAM, NED, PET or VIC), and the following PCR cycling parameters were used for selective amplifications: an initial cycle at 94°C for 30 s, 65°C for 30 s, and 72°C for 60 s.
Despite warnings that steroids increase the rate of heart attacks, the amount of cholesterol in the body and the risk of sterility, the player takes an initial cycle, either ingesting the steroids orally or injecting them into his buttocks.
Of the 244 randomised patients, 4 did not commence treatment 2 from arm A and 2 from arm E. Of the remaining 240, two patients (0.8%) received a single initial cycle of LV5FU2 alone before commencing their allocated regimens.
The patients randomised in both arms will benefit from a structured initial cycle.
31 Patients were treated with either everolimus or bevacizumab for a 21-day initial cycle before receiving a combination of both drugs.
The 2nd step PCR reaction (95°C for 30 seconds, 60°C) was run for 40 cycles after an initial single cycle of 95°C for 15 minutes to activate the Taq polymerase.
PCR cycling parameters included an enzyme activation cycle at 50°C for 2 minutes and an initial denaturation cycle at 95°C for 2 minutes followed by 45 cycles at 95°C for 15 seconds and 60°C for 1 minute.
