Absorbance assay at 280 nm. This method is just as convenient as for absorbance at 280 nm. It may be preferred if there is excessive contamination by nucleic acids, since nucleic acids absorb very little radiation at 205 nm. Setting the wavelength is a bit tricky since 205 nm is right on the shoulder of the protein peak. - [Read Absorbance Assay 205 nm]
Absorbance assays are fast and convenient, since no additional reagents or incubations are required. No protein standard need be prepared. The assay does not consume the protein. The relationship of absorbance to protein concentration is linear. Because different proteins and nucleic acids have widely varying absorption characteristics there may be considerable error, especially for unknowns or protein mixtures. - [Read Absorbance Assay 280 nm]
Protocol for Agrobacterium-mediated transformation in rice. Agrobacterium-mediated rice transformation method that is applicable to easily cultured varieties in addition to elite japonica varieties that are more difficult to culture. Using this method, transgenic rice plants can be obtained in about 2–3 months with a transformation frequency of 30–50%, both in easily cultured varieties and recalcitrant elite japonica rice. - [Read Agrobacterium-Mediated Transformation in Rice Protocol]
Protocol presents the amplification of insert end sequences from bacterial artificial chromosome clones using TAIL-PCR. The amplified products are suitable as probes for chromosome walking and genome mapping and as templates for direct sequencing. The
protocol has been used in rice genome studies. - [Read Amplification of Insert End Sequences from BACs Clones by Thermal Asymmetric Interlaced PCR]
