- Description
- NOTICE: THIS IS A REQUEST FOR INFORMATION ONLY. The information provided in response to this notice will assist the Government in determining the extent of the small business and socio-economic market for the type of work described herein. The intent of the announcement is to identify sources that are qualified business concerns capable of furnishing the National Marine Fisheries Service with hormone analogs that can be used to improve reproduction of fish raised for aquaculture or for conservation purposes. The aim of this project is to develop methods to produce gonadotropin analogs that are hybrids of hCG and fish gonadotropins and are biologically active in variety of fish species. To accomplish this goal, recombinant fish gonadotropin analogs must be tested for their ability to regulate ovarian and testicular function. The contractor must have purified native salmon FSH, LH and TSH, and immunoassays for steroids and thyroid hormones listed below to successfully complete this work. There are two tasks required for this work. In addition, all assays must be done using coho salmon or tissues from this species. 1) Test up to 40 recombinant salmon gonadotropin analogs for steroidogenic activity using bioassays with coho salmon ovarian tissue. These bioassays should be done using cultures of coho salmon ovarian follicles and measuring the amount of steroid released into cell culture medium by radioimmunoassay. Three types of steroidogenic activity must be determined: a. Assay the ability of analogs to stimulate in vitro production of estradiol-17 beta by vitellogenic coho salmon ovarian follicles and to compare their activities to that of purified native forms of coho salmon FSH and LH from salmon. At least 4 concentrations of each should be tested. b. Assay the ability of analogs to stimulate in vitro conversion of 17-alpha hydroxy progesterone to 17-alpha, 20-beta hydroxy-4-pregnen-3-one by coho salmon ovarian granulosa cells and to compare their activities to that of purified native forms of FSH and LH. Cultures of granulosa cells from preovulatory ovaries of coho salmon must be used for this assay since it specifically tests the LH activity of the preparations. Other stage ovaries cannot be used for this assay. At least 4 concentrations of each should be tested. c. Assay the ability of analogs to stimulate in vitro production of 11-ketotestosterone by testicular tissue from coho salmon in early stages of spermatogenesis and to compare their activities to that of purified native forms of coho salmon FSH and LH from salmon. At least 4 concentrations of each should be tested. 2) Test up to 40 recombinant salmon gonadotropin analogs for thyrotropic activity using in vivo bioassays with juvenile (no greater than 20 g body weight) coho salmon. These bioassays should quantify the changes in plasma thyroxine levels after two injections of analogs (3 doses/analog) compared to purified native salmon thyroid stimulating hormone (TSH) and bovine TSH. The Research Scientist/Engineer must have the following: Education 1) Person overseeing the work -Ph. D. in biological sciences 2) Person performing the bioassays - M.S. or Ph.D. in biological sciences Experience 1) Vendor must have experience with culturing salmon or trout ovarian follicles and isolation of granulosa cells from the ovary and measuring steroid production by these cells. 2) Vendor must have experience in staging salmon oocytes so that bioassays are performed at the appropriate stage 3) Vendor must have experience and have reagents necessary to perform radioimmunoassays or enzyme immunoassays to measure estradiol 17-beta and 17a, 20b-dihydroxy-4-pregnen-3-one in culture medium. Must have ability to run thyroxine immunoassays to measure blood levels of thyroid hormones. Reagents- The vendor must have purified native salmon gonadotropins (FSH and LH) to compare activities of analogs to native hormones. Period of performance is from date of award through June 30, 2010. The North American Industry Classification Code (NAICS) is 541712 with a size standard of 500 employees. All contractors doing business with the Government are now required to be registered with the Central Contractor Registry (CCR). In addition, completion of the online representation and certifications application (ORCA) is required. NOTE: THIS SYNOPSIS IS NOT CONSIDERED A REQUEST FOR PROPOSAL BUT A REQUEST FOR INFORMATION ONLY. No solicitation document is available. No contract will be awarded on the basis of responses received to this notice. All interested parties must respond to this announcement by December 30, 2008. Documentation to support the contractor's capability, education and experience must be in writing and include the contractor's name, address, point of contact, telephone number, DUNS Number, CCR Cage Number, business type and size, i.e., small, large, non-profit, educational, etc.; and a brief narrative regarding its capability to provide the services as described above. Any response that does not include this information will not be considered. The Government will review each response to determine if the contractor has the experience, knowledge, and capability to perform the services as specified above. Detailed information must be submitted by email to the address noted below by 2:00 PM local Seattle time (PDT), December 30, 2008. Email Address: Mona.M.Ash@noaa.gov. Questions of any nature must be addressed in writing as NO TELEPHONE INQUIRIES WILL BE HONORED.
