Cytokines are hormone like molecules that can control reactions between cells. They activate immune-system cells, such as lymphocytes and macrophages. Cytokine bioassay services are offered by many organization. The organization offers to the scientific community a unique service, Cytokine bioassays including, proliferation & neutralization, in vitro cytotoxicity, complement dependent cytotoxicity (CDCC), agonist & Antagonist screening, as well as Cytokine release assay. They assure strict confidentiality and superior execution which will be delivered on a timely basis & cost effective manner. The expected turnover time per assay is less than two weeks, and a written report including methods, results & conclusions will be issued. The organization is determined to maintain the highest standards & deliver the highest quality products and services. Most of the bioassays are based on a colorimetric method of measuring cell activity using a non-radioactive substrate. This assay has been proven to be equivalent to the [3H]thymidine incorporated assay (cell signaling applications guide, Promega Corporation). The compound and the standard (if required) are reconstituted, serial diluted & incubated with the cells over a 20 to 96 hour period

The term probiotic is generic and all-encompassing, to include microbial cultures, extracts & enzyme preparations. As such, the Office of Regulatory Affairs of the Food & Drug Administration (FDA, 2003 ), as well as the Association of American Feed Control Officials (AAFCO, 1999 ), have recommended the term direct-fed microbials (DFM) be used to describe feed products that contain a source of live, naturally occurring microorganisms. Feeding DFM generally results in a 2.5 to 5% increase in average daily gain and an approximate 2% improvement in feed efficiency in feedlot cattle. DFM promotes the absorption & digestion of feedstuff, growth and development. Improve the meat quality and intestinal tract condition, temper the bacteria balance, increase immune function & anti-virus ability of the organism. Increase egg laying rate and poultry fertility rate.
