新型GeneChip掃描儀(GCS) 3000 7G在分析基因芯片方面，能夠比以前型號的機(jī)器分析數(shù)據(jù)多出50%。
這種新型掃描儀具有掃描更小的芯片功能，范圍從2.5μm~0.51μm，支持最新的高密度GeneChip芯片，從tiling、全外顯子到單核酸多態(tài)性基因分型研究。這種新型掃描儀是Affymetrix公司的產(chǎn)品。設(shè)計用于各種操作的峰掃描，包括RNA表達(dá)和DNA分析。這種掃描儀與以前使用GeneChip基因芯片、以及其他Affymetrix公司的設(shè)備和軟件得到的資料都兼容。
GCS 3000 7G的特殊之處包括：一種新型雙處理器工作站以及軟件，可以升級每次實驗可以處理5倍的數(shù)據(jù)，改良的自動聚焦運算法則用于掃描標(biāo)準(zhǔn)尺寸的49格式的基因芯片，比原來的GSC要快30%。除此之外，一種擁有的Flying Objective掃描系統(tǒng)能夠確保影象的均勻和精確。高數(shù)字光圈光學(xué)結(jié)構(gòu)為整個視野提供協(xié)調(diào)的激發(fā)和發(fā)射途徑。
Affymetrix公司產(chǎn)品技術(shù)組. 副總裁Chip Leveille指出：“我們設(shè)計最早的GCS 3000向前兼容，只需要一個簡單的升級就可以支持下一代高密度基因芯片，因為GeneChip技術(shù)一直在不斷進(jìn)步。”
 
Gene-Sequence Scanner Analyzes More Data
 
The new GeneChip scanner (GCS) 3000 7G allows the analysis of microarrays that feature 500% more data than previous generations.

With the ability to scan smaller features, ranging in size from 2.5 μm to 0.51 μm, the new scanner supports the latest high-density GeneChip microarrays for tiling, all-exon, and single nucleotide polymorphism (SNP) genotyping research. The new scanner is the product of Affymetrix, Inc. (Santa Clara, CA, USA). It is designed to provide peak scanning performance for all operations, including RNA expression and DNA analysis. The scanner is compatible with data from previous experiments using GeneChip microarrays as well as other instruments and software of Affymetrix.

Specific features of the GCS 3000 7G include a new dual processor workstation and software updates for processing and analyzing up to five times as much data per experiment, and an improved autofocus algorithm for scanning standard-size 49-format microarrays 30% faster than the original GSC. In addition, a patented scanning system called the Flying Objective provides image uniformity and accuracy. High-numerical-
aperture optical architecture provides consistent excitation and emission paths over the entire scan field.

“We designed the original GCS 3000 to be forward-compatible, requiring only a simple upgrade to support the next-generation of high-density microarrays that develop as GeneChip technology continues to advance,” observed Chip Leveille, vice president of Product Technologies Group, Affymetrix.
