Dog Hair Extract Study

2015-05-14 19:38:23 | BioPortfolio


Liquid allergen extracts contain proteins, such as (but not limited to) tree, weed, cat, cockroach, and nuts, and are used to identify allergies by observing the body's reaction to the introduction of extract underneath the skin. There are a few dog allergen extracts commercially available in the US for allergy testing; however, none of these products are standardized, meaning they are not required to be the same strength. Because some extracts are not as potent (strong) as others, it's possible that some patients' allergies are misdiagnosed. Typically, the most potent (strong), but safe extract should be used so that allergic patients are correctly diagnosed.

The purpose of this study is to compare the safety and potency of an investigational (not approved for use by the United States Food and Drug Administration [FDA]) dog allergen extract with two commercially available dog extracts, which are of differing potencies.


This study is designed to assess the potency of a modified dog hair and dander extract in comparison with the two commercially available dog hair and dander extracts. This is a pilot study to estimate a target strength of dog extract in order to proceed to further studies.

Medical and Biotech [MESH] Definitions

A dehydrated extract of thyroid glands. After the removal of fat and connective tissue, the extract is dried or lyophilized to yield a yellowish to buff-colored amorphous powder containing 0.17-0.23% of iodine.

Hair grooming and cleansing aids or other products meant for topical application to hair, usually human. They include sprays, bleaches, conditioners, rinses, shampoos, nutrient lotions, etc.

Auditory sensory cells of organ of Corti, usually placed in one row medially to the core of spongy bone (the modiolus). Inner hair cells are in fewer numbers than the OUTER AUDITORY HAIR CELLS, and their stereocilia are approximately twice as thick as those of the outer hair cells.

Sensory cells in the organ of Corti, characterized by their apical stereocilia (hair-like projections). The inner and outer hair cells, as defined by their proximity to the core of spongy bone (the modiolus), change morphologically along the cochlea. Towards the cochlear apex, the length of hair cell bodies and their apical stereocilia increase, allowing differential responses to various frequencies of sound.

A dehydrated extract of thyroid glands from domesticated animals. After the removal of fat and connective tissue, the extract is dried or lyophilized to yield a yellowish to buff-colored amorphous powder containing 0.17-0.23% of iodine.
