Introduction
Peanuts are considered one of the most allergenic foods, as they are one of the eight major allergens that must be listed on the packaging of foods in the United States (FARE)*. Peanuts cause roughly 0.5% to 2% of food allergens worldwide (Cabanos and other 2011)*. These reactions caused by peanuts can be anywhere from a mild skin reaction to deathly anaphylactic shock. Although peanuts cause allergies, they are often used in food processing. They provide important nutrients such as fats and proteins. While there are other foods that can provide similar nutrients (i.e. soybeans, beans, etc.), peanuts are still commonly used.
The proteins found in peanuts are the cause of peanut allergies. There are a total of thirteen different

These seeds were germinated for around five to ten days, depending on the conditions applied. The reasoning behind the germination conditions is not fully explained. After germination, all parts of the plant, including the germinated seeds, cotyledons, plumules, hypocotyls and radicles were separated from one another to be tested. The main methods used for this study were ELISA and Western blot analysis.
Proteins from the peanut samples are extracted for comparison from short-term germinated. The protein concentration is determined using Bradford analysis.
The next step is to purify the protein Ara h1 using DEAE Fast Flow and high performance liquid chromatography. The purity of Ara h1 was measured by SDS-PAGE gel stained with Coomassie Brilliant Blue.
Rabbits were used for the testing of antibodies against Ara h1. The purified Ara h1 was injected into rabbits.
The ELISA method was used to examine the immunoreactivity of Ara h1. The results were read in a spectrophotometer at 450 nm. The purified Ara h1 proteins were used to construct a standard curve.
Electrophoresis was used to examine the whole peanut protein extracts.
Western blotting was used to detect Ara h1 or its protein fragments.
All of these methods seemed to be reasonable and the most efficient for what needed to be
Digestion of the haemolytic and non-haemolytic cells allowed for easier identification of fragments during electrophoresis analysis. Lane 12 in figure 3 show the size markers of SPP1 digested with EcoR1 while lanes 6 and 7 show samples of pK184hlyA and pBluescript digested with EcoR1 and Pst1. Lane 4 was loaded with plasmid DNA from haemolytic cells digested with EcoR1 and Pst1 while lane 5 was loaded with EcoR1 and Pst1 digested DNA from non-haemolytic cells. There was a lack of technical success in both lanes due to no bands appearing in lane 4 and only a single band appearing in lane 5. Theoretically, two bands should appear in both lanes after successful to allow for fragment identification. A possible explanation for the single, large fragment in lane 5 is that successful digestion did not take place and the plasmid was only cut at one restriction site leaving a large linear fragment of plasmid DNA. The absence of bands in lane 4 could be because there was not enough plasmid loaded into the lane. Another possibility could be that low plasmid yield as obtained when eluting the experimental samples in order to purify it. Lanes 8 and 9 belonged to another group and show technical success as two bands were present in both the haemolytic (lane 8) and non-haemolytic (lane 9) lanes. If the
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
These lollipops contain more calories, more sodium, and absolutely more high fructose corn syrup. This new brand has become no where near as popular as the family favorite Dum-Dums which have been around since 1906. Our world renowned Dum Dums contain no peanuts or tree nuts, which is excellent to the 3 million Americans with peanut allergies, no milk or eggs, no fish, and a large majority thank the fact that dum dums are wheat and gluten free. The 15 million people with food allergies can easily enjoy a majority of of dum dum flavors. After all, doctors always give you dum dums at the end of your appointment.
Following my first sip of milk at the age of one, with the resulting hives and coughing that ensued, I involuntarily joined the community of fifteen million Americans afflicted by food allergies. Living everyday with additional allergies to peanuts, tree nuts, and shellfish has, out of necessity, sharpened my compulsiveness with ingredients and food preparation, but furthermore has spurred me to intervene on behalf of fellow members in this emerging epidemic. The Food Allergy Research and Education (FARE) national organization has been a source of education and support in my own life, and subsequently has aided my efforts to raise awareness among peers, and to nurture my advocacy involvement.

Food allergies are the most controversial allergy-related topic right now. It's controversial because of several facts like:
Thesis Statement: Peanut allergy, a type of allergy that is very common these days among children and which results in many deaths yearly, now might have a cure, and today I will talk about the peanut allergy and its symptoms and the new proposed cure for it.
Corn and soy: are other common allergens. Soy in the form of soy lecithin and corn as corn syrup are popular ingredients found in chocolates.
First, “What are food allergies”? , food allergies are when the body overreacts and become highly sensitive to

Some parents of children with peanut allergies are not asking their school to ban peanuts. They consider it more important that teachers know which children are likely to have a reaction, and how to deal with it when it happens; i.e., how to use an Epipen.
Human race is known to have developed numerous allergies to various known and unknown allergens. An extreme allergic reaction which can be “life-threatening”. (Mydr.com.au, 2014) is referred to as Anaphylaxis.It is a “medical emergency”(Lloyd & Sisman,2013).Statistics indicate that maximum deaths occur due to allergic reactions of various medicines. The other causative agents can be insects, food, latex, hair dye, etc(Lloyd & Sisman,2013). The most common trigger to stimulate anaphylaxis among children are food products such as peanuts, dairy, seafood etc. Exposure to any of these allergens can result in severe anaphylactic attack within 20 minutes.(Australian Resuscitation council, 2012).However the doctors discuss the history of symptoms occurring in children suffering with peanut allergy before declaring them to be anaphylactic and prescribing medication. (Unknown, 2014). Symptoms of anaphylaxis may occur in varied forms depending upon the severty of the reaction. For instance in mild cases swelling of lips, eyes or face occurs along with hives, rash, tingling of mouth and vomitting accompanied with abdominal pain. Nevertheless in extreme conditions the former symptoms may be accompanied with noisy breathing, wheezing, hoarseness and unconsciousness. (Lloyd & Sisman,2013).
On the contrary, plant protein sources, such as beans, lentils and nuts are considered to be incomplete, as they lack one or more of the essential amino acids that your body needs (1).
... If further research is to be done, I recommend that it should explore and compare other kinds of peanut butters. Organic peanut butter, creamy peanut butter, sugar-free peanut butter, sodium-free peanut butter and natural peanut butter could be investigated.
Nutrition. Peanut butter is well known because it contains many vitamins, proteins, and fiber. Nowadays, it is very important for everyone to start a day with a meal that it is rich in vitamins, nutrients, and provide energy throughout the day. Besides obesity and malnutrition is a worldwide problem.
