GMF Detection Kit


GMF DETECTION KIT

Introduction
Among application of biotechnology to food is generic modification (GM), also known as genetic engineering, genetic manipulation, gene technology or recombinant DNA technology. The collective term “Genetically Modified Organisms” or GMOs is used frequently in regulatory documents and in the scientific literature to describe plants, animals and microorganisms which have had DNA introduced into them by means other than by combination of an egg and a sperm or by natural bacterial conjugation.

With the increase availability of genetically engineered products, especially their usage as food, it becomes a necessity to have the proper techniques for the identification of such materials as a means for controlling adherence to safety requirements and other regulations. Legislation was enacted worldwide to regulate the presence of genetically modified organism (GMO) in food and food ingredients. The procedure obliges the development of a reliable and sensitive method for GMO detection in order to verify its compliance with local act and labeling requirements.

Plymerase Chain Reaction (PCR) has already been proven as a good analytical method for the detection of specific target gene or DNA fragment in many diagnosis applications, through its simplicity, specificity and sensitivity. In this invention, the PCR technology was successfully used to produce GMO detection kit for etecting foods and food ingredients that contained genetically modified soya bean. This detection kit can be applied reliably with repeatability, and is well suited for the use within a framework of statutory control activities with respect to labeling obligations, surveillance and monitoring.

Description of Invention
The invention utilized the PCR technology in detecting the presence of specific DNA sequence of transgene in the tested sample that contained genetically modified organism. The unity of this invention was based on two set of primers concurrently in a single PCR reaction in order to target both the transgene as well as the soya bean gene.

The primer set targeted at the transgene was designed based on the 35S promoter sequence, the common promoter DNA sequence for various types of transgenic soya bean. While the primer set targeted at the soya bean gene was the single copy internal gene. Since the detection kit was also aimed for GMO detection in processed foods, it was designed to target the PCR fragment size at about 150bp, thus enable it to detect the broken DNA fragment caused by the extreme condition in food processing.

Disposable Immuno-Sensor For Detection Of Antibiotic Residues In Livestock Produces


DISPOSABLE IMMUNO-SENSOR FOR DETECTION OF ANTIBIOTIC RESIDUES IN LIVESTOCK PRODUCES

Introduction
Most of the antibiotic products were originally introduced to improve human and animal health. Abuse of these antibiotic can have harmful effects on animal and humans, where it can accumulate in animal tissues and can enter the food chain once the animal is slaughtered. Various regulatory bodies have acted to control the use of these antibiotics in farming and subsequently creating the need for sensitive, reliable, cost-effective methods for the detection of antibiotics. Simple disposable electrochemical immuno-biosensor using screen-printed electrode (SPE) coated with antibodies was developed for antibiotic detection. This innovation was found to be more efficient, sensitive, specific and simple to use. It is capable of handling many samples at lower costs. The innovation is also very useful in development of commercial biosensor for quick detection of chemical residues in poultry and other livestock meat.

Description of Innovation
This innovation is based on the specific antibody against streptomycin antibiotic that was coated on the surface of the screen printed electrode which was connected to the electrochemical analyser (potentiostat), together with a Ag/AgCl reference electrode and a Pt auxiliary electrode. The three electrodes were placed in a stirred 5 ml vessel. The electrodes were operated using the cronoamperometric method, which has time base modes in seconds.

The major advantages of SPE coated with antibody are:
a) Antibodies are in a more stable environment upon immobilization in the polymeric framework, thereby creating a stage and thus protecting the antibody from aggregation and unfolding on the surface of the SPE.

b) Antibody could recognize specifically their antigens. Thus in this case coated SPE could detect their specific antibiotics.

Kenaf Seed Thresher


KENAF SEED THRESHER

Background
Kenaf is grown from seed and a large quantity of seed supply is needed for commercial production. Kenaf seed production is labour intensive especially in the harvesting and seed processing aspects. Besides, threshing kenaf seed causes severe skin irritationto the field workers. Mechanization of seed production is needed to overcome some of these constraints. A seed threshing machine is recommended to facilitate smallholders to solve labour problems, reduce seed production cost and skin irritation problem.

Description of Innovation
A seed thresher machine, modified from a soya bean thresher, has a small 4-stroke gasoline engine, 2.7 HP Robin EY15 as main power source. It is designed to thresh kenaf seed. The machine has three unique mechanical processes:

# The first process comprises two closed range spike-tooth cylinders with adjustable threshing space for pulling function of kenafstems and at the same time threshing the capsules at a rotation speed of 230 rpm. The adjustable space is supported by 2 pairs of springs to accommodate various sizes of kenaf stems.


# The second process is to separate the seed from capsules usin a beater which hit the press capsules in the closed part at a spindling speed of 460 rpm. The seed is beaten out of capsules while the stumps are then pushed out from the thresher.

# The final process is cleaning. The seed, which have been beaten out, will fall down into the sieve which is located under the beater. The sieve screen filters the seed from the chaffs such as cores, capsules, leaves and other unwanted materials. The sieve is elongated to collect the seed, while the trash and debris are forced out together with the stumps. The machine is mostly recommended for seed crops harvested during dry season.
