Fluorescent IN SITU Hybridization is a relatively new technology utilizing fluorescently labeled DNA probes to detect or confirm gene or chromosome abnormalities that are generally beyond the resolution of routine cytogenetics. FISH is used in interphase cells to determine the chromosome number of one or more chromosomes as well as to detect some specific chromosome rearrangements that are characteristic for certain cancers. Fluorescent in situ hybridization is a complex test that detects mutations in chromosomes for a number of different types of cancer.

Fluorescent microscope works on the principle that an object is emitting light. It is designed to collect an optimal signal while minimizing background illumination. Two types of illumination exist for fluorescence microscopy: transmitted illumination and incident illumination. Most fluorescent microscopes use epifluorescence, meaning that the excitatory light is transmitted through the objectives onto the specimen and not through the specimen.

Follicle stimulating hormone (FSH) is a glycoprotein gonadotropin secreted by the anterior pituitary in response to gonadotropin-releasing hormone (GnRH), which is released by the hypothalamus. In women, FSH helps control the menstrual cycle and the production of eggs by the ovaries. A FSH test measures the amount of follicle stimulating hormone in a blood sample. This test is used to evaluate to woman's egg supply (ovarian reserve) and man's low sperm count. It is done to determine whether a child is going through early puberty.

Follicle Stimulating Hormone Fertility Tests Kit is used to test for infertility and menopause. FSH tests help women diagnose infertility issues by indicating elevated levels of the hormone FSH.

Follicle Stimulating Hormone is a naturally occurring hormone. FSH is important in the development of follicles (eggs) produced by the ovaries. FSH is used for the development of sperm. Follicle stimulating hormone is used together in the treatment of infertility. Follicle stimulating hormone is used to stimulate the development of multiple eggs for in vitro fertilization.

Four Tiered Pipette Rack is made for disposable plastic pipettes. It is designed for removal of pipettes from the right side.

Free estriol (E3) is the principal estrogen produced during pregnancy. It is produced by the placenta from dehydroepiandosterone sulfate derived from the fetal liver and adrenals. The test is used as part of the triple marker screen (in association with alpha fetoprotein and chorionic gonadotropin) for Down syndrome.

Free T3 is an important hormone in the regulation of metabolism. Free T3 test measures the amount of T3 hormone in the blood. It is measured as part of a thyroid function evaluation. Most of the thyroid hormone made in the thyroid is in the form of T4. The body's cells convert the T4 to T3, which is the more active hormone. It is the most powerful thyroid hormone, and affects almost every process in the body, including body temperature, growth, and heart rate.

Free T4 is used as a biochemical indicator of thyroid function, and aids the diagnosis and monitoring of both hyperthyroidism and hypothyroidism. It is an amine hormone synthesized and secreted by the thyroid gland and a precursor to triiodothyronine. It is metabolically active form of the hormone.

Freeze-dried reagent is preferably for use in clinical diagnosis, which enables a simple and rapid determination of components active in proteolysis. It is used for the diagnosis of trypanosomiasis hemgglutination test and for the detection of trematode antigens.

FSH Enzyme Immunoassay Test Kit is based on the principle of a solid phase enzyme-linked immunosorbent assay. The assay system utilizes mouse monoclonal anti-FSH for solid phase immobilization and sheep anti-alpha FSH in the antibody-enzyme conjugate solution.

Fume Hoods are used when chemical reagents produce a hazardous fume. These fume hoods operate more efficiently and with less noise at lower static pressure values. Fume hoods are an integral part of a chemical hygiene program as they prevent exposures by removing vapors, gases and particulates from the work area. Fume hoods are an important engineering control designed to protect laboratory workers from potential chemical exposures.

Gamma-GT is a test to measure the amount of the enzyme GGT in the blood. It is used to detect diseases of the liver, bile ducts, and kidney. It is also used to differentiate liver or bile duct disorders from bone disease. It participates in the transfer of amino acids across the cell membrane, and in glutathione (an anti-oxidant) metabolism.
