The requirement for Rad1– Rad10 could be to remove the heterology presented by the HO cs sequence that would prevent pairing between the 3′ end and donor template or to cleave at the heterology boundary if the D-loop intermediate branch migrated to the end of the homology shared by the lys2 sequences (Fishman-Lobell and Haber 1992).
The fixed-circuit approach needs templates, or masks at $1m for each new circuit, making it difficult for product designers to quickly adapt to changing markets and technology formats.
Moreover, unusual banding patterns in the HindIII HDR assay implied the presence of a concatemerized HDR template or non-specific recombination products, at least with short sequences as employed here.
DNA substrates were generated by annealing a 5′-[P]-radiolabeled primer with either the control 40-mer template or damaged 40-mer-8oxodG template at a molar ratio of 1.00 1.15.
To obtain folate-coated nanoparticles, a folate ligand was added to either the microemulsion templates or nanoparticle suspensions at 25 °C.
Photochemically synthesized cobalt oxide hydroxide (PCOH) under UV light has been successfully achieved without the addition of surfactants, templates, or organic solvents at ambient temperatures.
Metastable γ-Bi2O3 were successfully prepared via a controllable, facile and mild solution precipitation synthesis method in ethylene glycol-water mixed solvent systems without adding surfactant or template agents, at 80 ℃ and ambient atmospheric pressure in 40 min.
Here we report a simple soft-templating approach for the synthesis of new mesoporous iron oxide materials having semi-crystalline pore wall by using an anionic surfactant sodiumdodecylsulfate as the structure-directing agent (SDA) or template at low temperature.
This product was obtained by using Cd(CH3COO 2·2H2O and NH2CONH2 as starting materials without any template, catalyst, or surfactant at a short time reaction and room temperature.
In this work, crystalline Gd3+-doped CdO micro-size layer has been synthesized by sol gel method, with cadmium nitrate (Cd(NO3 2·4H2O), Gd2O3, and ethylene glycol (C2H6O2) as raw materials without using any catalyst or template at a heat treatment temperature of 900°C with increasing temperature rate of 15°C/min for 12 h, which is a very simple and economical method.
