DETECTION OF PIG DNA FRAGMENTS IN HALAL UNLABLED LIPSTICK SAMPLES USING CONVENTIONAL PCR
نویسندگان
چکیده
From a Muslim perspective, it is very important to know the content, raw materials, and processing of materials used in cosmetic products used. One type cosmetics that most often lipstick. However, many lipsticks circulating Indonesia are not equipped with halal logo. ingredients for lipstick pork derivatives. These pig derivatives can be detected using PCR. Based on this background, study aims test presence DNA samples have been certified market 4 combinations fragments coding primers by conventional PCR method. Five commercial were selected purposive sampling. isolation was carried out according Wizard Promega Universal Kit. The process temperature optimization as follows: Predenaturation 98oC: 2 minutes, denaturation 95oC: 30 seconds, Annealing 61oC: Extension 72oC: 40 Postextension 3 minutes. results showed 5 tested kinds primer combination, none suspected contain DNA. difficult step sample detection process. Even though result negative, necessary carry further tests which become Gold Standard DNA-based testing Real Time

Quantification and Optimization of Candida albicans DNA in Blood Samples Using Real- Time PCR
Background: Candida albicans (C. albicans) is a major cause of candidaemia in people with impaired immunity. Blood culture is a “gold standard” for candidaemia detection but is time-consuming and relatively insensitive. We established a real-time PCR assay for C. albicans detection in blood by LightCycler PCR and melting curve analysis. Methods: Five milliliter blood samples from...
متن کاملComparison of ELISA and PCR Assays for Detection of Pork Adulteration in Halal-Labelled Beef Products
Background: Food adulteration with pork in processed beef products is one of the most serious issues in a food sector in a Muslim-majority country since it is related to religious food ethics regarding the halal products. The goal of this research is to test the suitability of ingredients in beef floss and its Halal by knowing the presence of pork DNA and protein in those products. Methods: Me...
متن کاملIs real-time PCR better than conventional PCR for Mycobacterium tuberculosis complex detection in clinical samples?
Cobas Amplicor MTB and later Cobas TaqMan MTB were used to test a very large series of consecutive specimens received for tuberculosis diagnosis. Performance parameters were estimated and compared overall and for separate specimen categories. Both systems showed excellent specificity, and that of TaqMan was the higher. The sensitivities were similar but satisfactory only with respiratory specim...
متن کاملPCR amplification of long DNA fragments.
The polymerase chain reaction (PCR) has recently evolved as a standard laboratory technique, popular in all areas of molecular biology research. However, the technique still has two limitations: the relatively low fidelity of Taq polymerase when compared with other polymerases (1), and its inability to efficiently amplify fragments higher than 3 kbp (2, 3). Although these two issues are irrelev...
متن کاملHalal authenticity of gelatin using species-specific PCR.
Consumption of food products derived from porcine sources is strictly prohibited in Islam. Gelatin, mostly derived from bovine and porcine sources, has many applications in the food and pharmaceutical industries. To ensure that food products comply with halal regulations, development of valid and reliable analytical methods is very much required. In this study, a species-specific polymerase cha...
