The analysis was carried out with a two step protocol starting with 20 seconds at 95°C, followed by 40 cycles of 1 second at 95°C and subsequent 20 seconds at 60°C.

After a decontamination step at 37°C for 5 min and inactivation of UNG enzyme at 95°C for 10 min, a two step protocol was followed for 40 cycles: 95°C for 20 s and 60°C for 40 s.
Basta and Hammer [ 48], established a two step protocol to isolate C3: PEG precipitation and fast protein liquid chromatography (FPLC) Mono Q ion exchange chromatography, using human and guinea pig.
In agreement with this interpretation, we found that a combination of Activin, FGF2 and BMP4 signalling efficiently induced mesendoderm differentiation using a three step protocol (Figure 3A).
In addition, we identified participants' apolipoprotein genotype by using polymerase chain reaction and Hhal digestion, as described by Tsukamoto et al. 30 Cognitive status was assessed with a three step protocol for the diagnosis of dementia: a screening phase, a clinical phase, and a differential diagnostic phase.
There has been no report of C3 isolation from goats, but in other ruminants, C3 has been purified from cows [ 51] using a four step protocol: polyethylene glycol precipitation and chromatography on DEAE-Sephadex A-50, CM-Sephadex A-50 and Sephacryl S-200.
To circumvent the above outlined limitations, we have developed a simple two steps protocol, relying on palladium catalyzed transformations.
Human BM-MSCs were trans-differentiated into hepatocyte by using two steps protocol: differentiation step followed by maturation step.
DNA was extracted with a novel two step protocol minimizing the amount of foreign (non Synechocystis) DNA based on the protocol of Franche and Damerval [ 49].
Real time PCR conditions included an initial denaturation step at 95°C for 10 min, followed by 40 cycles of a two steps amplification protocol: denaturation at 95°C for 15 s and annealing/extension at 60°C for 1 min. Relative expression values of different genes were calculated following the ΔΔ C T method [ 31, 32], using RPO21 as reference gene.
