How is Horse Serum Made? A: Horse Serum is sourced from healthy donor horse herds that are regularly inspected and tested for infections equine diseases, including Equine Infectious Anemia (EIA) .

What is horse serum?

Horse Serum is broadly used as a blocking agent in immunoassays. Horse Serum contains more immunoglobulins than fetal bovine serum (FBS), has an increased protein content, and is a cost-effective alternative to fetal bovine serum.

What is horse serum allergy?

When a person is exposed to horse albumin, it can trigger the immune system to create antibodies known as IgE antibodies. These antibodies trigger an allergic response that can cause symptoms associated with horse allergies, including sneezing and coughing.

Does horse serum need to be heat inactivated?

In general, it is not necessary to use heat-inactivated serum to culture most cell types. We recommend using heat-inactivated serum when working with immune type cells or for immunological applications.

What do they do with horse sperm?

Semen collection for the purpose of reproductive evaluation or for use in artificial insemination is widely practiced in modern horse breeding. Although semen collection can be performed on jump mares, the standard accepted method is to train the stallion to mount a phantom, or dummy.

Is tetanus vaccine still made from horse serum?

Tetanus antitoxin is obtained from the blood serum of horses previously inoculated with tetanus toxoid. From horsehide a number of articles are manufactured, including fine shoes and belts.

When was horse serum used?

The development of equine neutralizing polyclonal antibodies (‘antitoxins’) to treat diphtheria and tetanus was first described in 1890 by von Behring and Kitasato, and equine antibodies were first used successfully to treat a child sick with diphtheria in 1891 [2].

Why is horse serum used in cell culture?

Horse serum has twice the protein content as compared to fetal bovine serum but is low in many trace elements that are required for optimal growth. When using horse serum, supplementing the basal medium with these trace elements can optimize the growth and count of cells.

What color is horse serum?

pale yellow
Generally a pale yellow to light amber liquid.

What percentage of people are allergic to horses?

Horse allergies affect as many as 5% of people with allergies. 1 Horse dander is able to travel long distances in the air and has been found hundreds of yards away from horse stables.

What is antitoxin from horse serum to human?

Antitoxin (toxin-neutralizing antibody) is produced from horses by injections of formaldehyde-inactivated DT, like that used in the human vaccine. Antitoxin was first used to treat diphtheria in 1891 and has a clinical efficacy of 97%.

What is the most toxic plant to horses?

Nine poisonous plants horses should avoid

• Ragwort. While ragwort has a bitter taste and is rarely eaten by horses when it is growing, when it is wilted or dried it becomes more palatable.
• Foxglove.
• Deadly nightshade.
• Buttercups.
• Acorns.
• Yew.
• Privet.
• Rhododendron.

How do you store horse serum?

To effectively preserve the integrity of animal serum, it should be stored frozen and protected from light. For stability and optimal performance, serum should be stored at -10 to -40 C and used prior to the labeled expiration date.

How do horses not overheat?

Horses normally cool themselves by sweating. The sweat evaporates from the skin surface and causes a cooling effect. Less sweat evaporates during times of high humidity. A horse that is working hard in a hot environment can lose 2 to 4 gallons of sweat per hour.

How do horses legs stay warm in the winter?

In extreme cold temperatures, blood-shunting mechanisms in the hooves alter circulation patterns to preserve body warmth.

How much sperm does a man produce when ejaculating?

A fertile male human ejaculates between 2 and 5 mililiters(ml) of semen (on average about a teaspoon). In each ml there are normally about 100 million sperm. If the concentration falls below 20 million sperm per mililiter there is usually some trouble with fertility.

How much is a race horse sperm worth?

Artificial insemination is also common in modern horse breeding, where high-quality horse semen is frozen in small tubes (known as straws) and stored for future use. For the two-time gold medal-winning show jumper Big Star, a single straw of his semen will set you back about $1,200.

How much is a bucket of horse sperm?

An analysis of one of the major semen sellers, with hundreds of horses on file, shows an average price of $873 per dose, with the most expensive horse semen costing $6,500.

Which vaccine is made from horse?

When compared to conventional vaccines, DNA vaccines offer two valuable advantages: shorter manufacturing times and no risk of causing disease in the patient. The West Nile Virus vaccine developed for horses occupies an important place in the history of immunology.

What vaccines have eggs in them?

Most flu shots and the nasal spray flu vaccine are manufactured using egg-based technology. Because of this, they contain a small amount of egg proteins, such as ovalbumin.
