Thank you for your interest in NeuroMab. Ordering directly from our corporate partner Antibodies Incorporated (AI) guarantees the lowest non-profit rates for NeuroMabs; you are welcome to request discounted prices from them but it is unlikely to be granted unless you are ordering a custom production batch (mg's worth). Our prices have increased every year since August 2010 in order to offset increased AI production costs and to support future NeuroMab projects --- our initial U24 NIH grant ended at that time and our renewed funding ends this year so we need to become self-sufficient if we are to continue to provide high-quality antibody at non-profit rates. Considering the cost of overseas shipping, please check what other NeuroMabs (e.g. immunoblot loading control N52A/42 or a TC supe sampler six-pack) may also be useful to you in order to make your total purchase more worthwhile.
