繼ZFN（Zinc Finger Nucleases）技術(shù)后，Merck在2013年推出新一代基因組編輯工具--CRISPR/Cas9，讓研究人員以更快、更經(jīng)濟(jì)的方式實(shí)現(xiàn)基因組特定位點(diǎn)的編輯。憑借過去10年在基因組編輯領(lǐng)域的豐富經(jīng)驗(yàn)積累以及專業(yè)的生物信息學(xué)平臺(tái)，Merck已經(jīng)成功設(shè)計(jì)出覆蓋人類，小鼠和大鼠三個(gè)物種的所有基因的CRISPR/Cas9載體，并可以提供在線定制服務(wù)，以及完整的CRISPR實(shí)驗(yàn)workflow解決方案。此外，默克與Sanger Institute合作開發(fā)了人、小鼠全基因組CRISPR 文庫，以幫助科學(xué)家實(shí)現(xiàn)基因功能的快速篩選、規(guī)模化的模型建立以及藥物作用篩選等。

• 高效：優(yōu)化的載體設(shè)計(jì)，大限度提高轉(zhuǎn)染效率，簡化篩選工作
• 特異：特殊的gRNA設(shè)計(jì)和雙切口酶系統(tǒng)，大限度提高特異性
• 全面：產(chǎn)品齊全，可提供質(zhì)粒、RNA、慢病毒載體、RNP等形式，涵蓋人、大鼠、小鼠、植物等多個(gè)物種，更有Sanger Arrayed和Broad Pools全基因組文庫以及重要通路的亞文庫
• 掌控：強(qiáng)大的慢病毒全基因組文庫可輕松進(jìn)行高通量篩選，全面掌控人或小鼠的基因組

The aim of molecular cloning is to insert the gene-of-interest (GOI) into a plasmid vector. This vector is then inserted into a cell that will express the protein encoded by the GOI. Once protein is expressed, the protein function can be studied as it affects the cell signaling, morphology or other aspects. Alternatively, the protein can be expressed in large quantities that can then be studied directly with other techniques. We have a wide variety of products for use across the cloning & expression workflow.

Biomatrica^® offers an innovative alternative to reliance on cold chain logistics

Biomatrica products enable researchers in academia, pharmaceutical drug development, and molecular diagnostics to stabilize ship and store biological samples for long periods of time with complete and rapid sample recovery, all at very affordable costs. Its SampleMatrix^® proprietary core technology stabilizes and protects biological materials at room temperature without degradation.

Sigma Life Science is committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product was Designed for Energy Efficiency. To see how Stanford incorporated Biomatrica Technology and saved substantial amounts of energy, see their published study:

Biomatrica technology enables safe storage of biological material at room temperature.

Consistent sample maintenance allows for experimental reproducibility, and therefore ensures reliability, speeds time to results, greatly reduces costs, and is an environmentally sustainable alternative to all forms of cold storage. This technology can be applied to thousands of currently available products in the biotechnology, diagnostics and pharmaceutical industries, and has direct applications for billions of samples generated from genome mapping, and sample archiving used for research into personalized medicine and forensics.

		Stabilize and archive gDNA at Room Temperature DNAstable® offers long-term preservation and stabilization of purified gDNA samples at room temperature in a dry-down matrix format. Available in single tubes, well plates (96 & 384) and tube-plates (96). DNAstable® Trial Kit DNAstable® Tube Kit DNAstable® 96-Well Plate DNAstable® Blood, trial kit DNAstable® Blood LD, 10mL bottle DNAstable® Blood LD, 100mL bottle
