May 11, 2006 Price Adjustment: Order by May 31, 2006 to Take Advantage of Current Prices Our goal at Nanoprobes is to provide you with the most effective means of finding the research answers that you seek. Our constant research and development has resulted in additional unique products and enhancements, and we look forward to additional new products shortly. We work consistently to keep prices affordable and competitive, and we have maintained our current price schedule since May 2000. However, rising costs and prices for our supplies and materials mean we now need to raise the prices slightly on most of our product lines, effective June 1. Therefore, if you use our products and need to make your funds go further, we encourage you to place your orders before May 31 so that you can take advantage of our current prices. Thank you for using Nanoprobes as your partner in research. We will continue to provide our valued customers with superior products and complete, timely technical support. Please keep reading our Newsletter for new developments and product releases planned for the coming months.

We have now implemented a new online ordering script which features improved protection from external attacks, and online ordering has been restored. For security reasons, the form no longer generates an e-mail receipt automatically; but you may request one from us using a checkbox on the order form.

Similar modifications have been made to our custom synthesis request form and to other forms on our site.

Important Notice: Custom Syntheses

Due to the heavy workload, we are currently only able to conduct custom syntheses of Nanogold® or colloidal gold-labeled antibodies. For other molecules, we recommend our labeling reagents: Monomaleimido-Nanogold®, Mono-Sulfo-NHS-Nanogold® or Monoamino-Nanogold®M.
