來自全球的科學家被邀請參加染色比賽，這項活動由Sigma-Aldrich公司贊助發起，這家公司主要提供生物化學和有機化學產品，以及在科學研究和基因研究中使用的試劑盒。

這次競賽主要是為了激發病理學以及染色科學領域的研究興趣。競賽作品是標準顯微鏡載玻片上的樣本，使用永久封片液封片，并用蓋玻片覆蓋。參賽的作品類別有三種：HE染色、特殊染色盒開放染色類別。投寄作品必須載2005年8月1日之前收到。Sigma-Aldrich公司網頁上提供了詳細信息。

Sigma-Aldrich公司技術市場部專家Mark Frei解釋說：“無論組織學是你的專業或者僅僅是你的愛好，我們都邀請你提供最得意的切片來獲取大家的注意并贏得可觀的獎金。”競賽優勝者名單將會在美國Fort Lauderdale舉行的2005年組織技術學會第31屆年會上公布。獲勝參賽作品的顯微照片將公布在Sigma-Aldrich公司的網頁上。

Histology Stain Contest
 
Scientists around the world are invited to participate in a stain contest, sponsored by Sigma-Aldrich (St. Louis, MO, USA), a provider of biochemical and organic chemical products and kits used in scientific and genomic research.

The contest is intended to encourage interest in the field of pathology and the science of staining. Entries should be in the form of specimens on standard glass microscope slides, mounted with permanent mounting media and cover-slipped. There are three categories of submission: hematoxylin and eosin stains, special stains, and an open stain category. Submissions must be received by August 1, 2005. More details are available on Sigma-Aldrich’s website.

“Whether histology is your profession or just a hobby, we invite you to enter your favorite slide to gain some well-deserved attention and possibly win valuable prizes,” explained Mark Frei, technical marketing specialist at Sigma-Aldrich. Contest winners will be announced at the 31st Annual National Society for Histotechnology Convention in Fort Lauderdale (FL, USA) on September 10, 2005. Micrographs of the winning entries will be posted on the Sigma-Aldrich website.
