<\/figure>\n<\/div>\n\n\nUsing<\/strong> our suite of previously developed in-house\u00a0radioimmunoassays, we are able to analyse your clinical trial samples or preclinical experimental samples. We have RIAs for\u00a0determining:-\u00a0 Plasma Renin Activity (PRA), Plasma Renin Concentration (PRC), Tissue renin, angiotensin-I, angiotensin-II,\u00a0angiotensin(1-7), vasopressin (AVP), atrial natriuretic peptide (ANP),\u00a0ppANP, urinary (human and rat) albumin. Our assays are\u00a0generally robust\u00a0and can\u00a0measure\u00a0in almost any species. Once\u00a0fresh\u00a0tracer is made and a standard curve\u00a0set\u00a0up, we can use our unlimited reagents to analyse thousands of samples for just $15 per sample. There are no RIA kit costs. All samples are assayed in duplicate against a full range (8 doubling steps) of standards in duplicate. Results are returned in a spreadsheet within a few days. Fifty\u00a0years experience\u00a0in RIA places our lab among the most reliable supporting the medical research community in this specialist field.\u00a0<\/p>\n\n\n\n We are happy to offer our RIA lab\u2019s expertise for analysis of any hormone etc. Often, we analyse for Aldosterone, Insulin, Cortisol, Melatonin (6 OH S metabolite) and many more, as long as the customer is happy to purchase the kit. We can even source the kit and pass our discounted rate on to you. <\/p>\n\n\n\n If you have expectations of a large number of assays and it would be financially non-viable to purchase kits, you should consider our next offer \u2013 to develop our own in-house assay for your analyte and pass the savings for very large projects on to you. Perhaps you have already started an assay and just need help refining it. Fifty years of experience in assay development makes us the experts in custom assays. <\/p>\n\n\n\n With 50\u00a0years’ experience\u00a0in developing\u00a0radioimmunoassays\u00a0for drugs,\u00a0hormones\u00a0and growth factors for medical research in cardiovascular disease, diabetes, infection etc.\u00a0ProSearch\u00a0is well placed for doing custom work for the clinical and experimental research community and drug companies. Radioimmunoassay is a highly specialized technique using the sensitivity of detecting specifically labelled molecules by their radioactive signalling and with the specificity of antibody recognition. No other technique to this day can measure picogram quantities (one millionth of one millionth of a gram) of substance with less than 0.01% cross reactivity to a poly peptide varying by only 1 amino acid (e.g.\u00a0the specificity of our Angiotensin II RIA to Angiotensin\u00a0(1-7). There is a need for this degree of specificity when assessing the activity status of the renin-angiotensin system (RAS) and the sensitivity when presented with only 20 \u00b5L of mice plasma.\u00a0<\/p>\n\n\n\n If you see the need for an assay for a drug, peptide, antibody or other substance, whether it be in plasma or tissue, of man or mouse, you should ask us about our ability to devise a method to measure it. We can raise an antibody (we are renowned for our exceptional antibodies), radiolabel the antigen, develop the assay to optimum sensitivity or precision, validate the assay in terms of collection protocol, stability of analyte, inter- and intra- assay variation, and hand over the assay with all documentation of performance, methods manuals etc. <\/p>\n\n\n\n ProSearch is essentially here to support the medical research community in any way it can. Our interests stem mainly from hypertension, diabetes and other cardiovascular diseases only because of historical involvement. We are happy to expand our application to any area of medical research but our focus is research, medical, measurement, peptides, cardiovascular, immunoassay, radioimmunoassay and radioligands. <\/p>\n\n\n\n Our association can be collaborative (e.g. grant sharing) or as a confidential service but as a privately funded facility we must recoup our running and infrastructure costs. Please contact us if you think we can help your research efforts. <\/p>\n","protected":false},"excerpt":{"rendered":" In-house RIA.
