Denaturation and Renaturation of DNA
Know More

The degree of renaturation after a given time depends on C 0, the concentration of double stranded DNA prior to denaturation, and t, the duration of the renaturation in seconds The concentration is measured in nucleotides per unit volume...

PCR Troubleshooting
Know More

To improve the PCR amplification of DNA fragments, especially fragments in the size range 100bp to 1000bp, a KCl concentration of between 70mM and 100mM is sometimes recommended For the amplification of longer products a lower salt concentration appears to be better...

Agricultural & Environmental Services Laboratories
Know More

The normal range of Cu in many plants is fairly narrow, ranging from 5 to 20 ppm When the Cu concentration in plants is less than 3 ppm in the dry matter, deficiencies are likely to occur When Cu levels exceed 20 ppm in mature leaves, toxicities may occur...

DNA Absorbance with STS
Know More

DNA measurements typically involve samples at the extremes of the concentration range with DNA suspended in solution at either very high or very low concentrations While dilution can be done with concentrated DNA solutions, low concentration samples present more of a challenge...

Protocol: a simple method for extracting ,
Know More

The addition of PVP into CTAB based extractions to absorb phenolics, preventing their oxidation that renders DNA unusable for downstream application, has been used successfully for other recalcitrant plant species [4, 5, 7, 9], typically at a concentration of 1-2% (w/v)...

DNA Extraction and Purification

DNA isolation methods are often modified and optimized for different cell typ Cetyltrimethylammonium bromide (CTAB) and guanidium thiocynate (GITC) are often included in protocols for DNA extraction from plant materials, and are discussed more in detail in section "DNA extraction from plant ,...

How i could determine DNA concentration
Know More

The DNA concentration is calculated as: OD at 260 * dilution factor * 50ng/ul In the example above the dilution factor is 100 There is a nice protocol from Vanderbilt which i've attached...

Nucleic acid quantitation
Know More

In molecular biology, quantitation of nucleic acids is commonly performed to determine the average concentrations of DNA or RNA present in a mixture, as well as their purity Reactions that use nucleic acids often require particular amounts and purity for optimum performance To date, there are two main approaches used by scientists to quantitate, or establish the concentration, of nucleic ....

An Easy, Rapid, and Cost
Know More

The highest DNA concentration was obtained from Punctelia subflava using our method, which was coincidentally one of the two lowest generated using the commercial kit (11 ng/mg and 12 ng/mg, respectively) (Table 1) Moreover, the A260/280 ratio ranged from 15 to 21 using both methods, indicating low protein contamination...
