Abstract:
DNA extraction from filter paper by using different methods was compiled through a thorough review of many research articles published in various journals. When performing malaria epidemiological surveys in remote area, it is difficult to collect blood samples and transport it. In field particularly in remote area where facilities for storing and processing of samples does not exist, there surveillance and diagnosis of malaria is very difficult. In this review we are focused upon four simple methods of DNA isolation from the field collected blood and mosquito abdomen blood meal spotted on Whatman No. 1 or No. 3 filter paper. The main DNA isolation methods are Chelex-100, Tris-EDTA (TE) buffer; Methanol based DNA extraction and Phosphate buffer saline (PBS) using Lysis buffer and Phenol-Chloroform method. Efforts have been taken to identify the methods which are cost-effective and take less time to extract DNA from dried blood spots (DBS) and whole mosquitoes. The purpose of this paper is to update the knowledge and find a method to extract DNA from DBS which will be specific, rapid, cost-effective, less time consuming and feasible for epidemiological survey in remote area.

03:08Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...

Indirect methods involve isolating the bound drug from its free form in biological samples such as blood, serum, or plasma. These techniques aim to measure the percentage of drugs bound to proteins. Equilibrium dialysis is a commonly used method where the free drug concentration at equilibrium is measured by separating the bound...
