MICROBExpress™ 细菌 mRNA 富集试剂盒可通过从总 RNA 中去除 rRNA 来纯化细菌 mRNA。提供足够从 10 µg 总 RNA 中各进行 20 次 mRNA 纯化的试剂。MICROBExpress 试剂盒的特点:

• 极大地提高了阵列分析和其他程序的灵敏度
• 从细菌 RNA 中去除 >95% 的 16S 和 23S rRNA
• 简单程序所需时间小于 2 小时
• 适用于多种革兰氏阳性细菌和革兰氏阴性细菌

快速纯化细菌 mRNA
直到现在都几乎无法从细菌中分离 mRNA。MICROBExpress 试剂盒使用一种新型技术从大肠杆菌和其他细菌种属的总 RNA 中去除 >95% 的 16S 和 23S rRNA。该试剂盒适用于从多种革兰氏阳性细菌和革兰氏阴性细菌中纯化 mRNA。使用 MICROBExpress 试剂盒分离得到的 mRNA 是用于合成阵列分析中标记 cDNA 的优良模板,也是定量 RT-PCR、Northern 应用和 cDNA 文库构建的理想选择。细菌 RNA 中 16S 和 23S rRNA 的高效去除能够显著提高下游程序的灵敏度(如图所示)。

从任何总 RNA 样品开始
这种宿主细菌细胞总 RNA 混合物可以通过多种 RNA 分离方法获得。MICROBExpress 试剂盒专门去除 rRNA;不会去除小 RNA(即 tRNA 和 5S rRNA)。使用缺少小 RNA 的总 RNA 作为 MICROBExpress 试剂盒的起始材料,可得到可能较高水平的 mRNA 富集(参见辅助产品)。在 MICROBExpress 试剂盒操作的第一步中,将总 RNA 与一组经优化的捕获寡核苷酸混合,它们可与细菌 16S 和 23S rRNA 结合。接下来,通过衍生的磁微珠从溶液中去除 rRNA 杂交。mRNA 保留在上清液中,并通过乙醇沉淀回收。

辅助产品
使用本试剂盒需要使用磁力架。它们有多种规格,包括单管磁力架(货号 AM10026)、6 管磁力架(货号 AM10055)和 96 孔磁力架(货号 AM10027 和 AM10050)。RiboPure™ 细菌试剂盒(货号 AM1925)适用于纯化无小 RNA 的总 RNA。可使用 MEGAclear™ 试剂盒从总 RNA 中去除小 RNA(货号:AM1908)。

Abstract
Structure and complexity of a bacterial transcriptome.
Authors:Passalacqua KD, Varadarajan A, Ondov BD, Okou DT, Zwick ME, Bergman NH
Journal:J Bacteriol
PubMed ID:19304856
'Although gene expression has been studied in bacteria for decades, many aspects of the bacterial transcriptome remain poorly understood. Transcript structure, operon linkages, and information on absolute abundance all provide valuable insights into gene function and regulation, but none has ever been determined on a genome-wide scale for any bacterium. ... More
Identification of new genes in Sinorhizobium meliloti using the Genome Sequencer FLX system.
Authors:Mao C, Evans C, Jensen RV, Sobral BW
Journal:BMC Microbiol
PubMed ID:18454850
Sinorhizobium meliloti is an agriculturally important model symbiont. There is an ongoing need to update and improve its genome annotation. In this study, we used a high-throughput pyrosequencing approach to sequence the transcriptome of S. meliloti, and search for new bacterial genes missed in the previous genome annotation. This is ... More
Validation of two ribosomal RNA removal methods for microbial metatranscriptomics.

Journal:Nat Methods
PubMed ID:20852648
The predominance of rRNAs in the transcriptome is a major technical challenge in sequence-based analysis of cDNAs from microbial isolates and communities. Several approaches have been applied to deplete rRNAs from (meta)transcriptomes, but no systematic investigation of potential biases introduced by any of these approaches has been reported. Here we ... More
Transcriptome analysis of a phenol-producing Pseudomonas putida S12 construct: genetic and physiological basis for improved production.
Authors:Wierckx NJ, Ballerstedt H, de Bont JA, de Winde JH, Ruijssenaars HJ, Wery J
Journal:J Bacteriol
PubMed ID:17993537
The unknown genetic basis for improved phenol production by a recombinant Pseudomonas putida S12 derivative bearing the tpl (tyrosine-phenol lyase) gene was investigated via comparative transcriptomics, nucleotide sequence analysis, and targeted gene disruption. We show upregulation of tyrosine biosynthetic genes and possibly decreased biosynthesis of tryptophan caused by a mutation ... More
Profiling Caenorhabditis elegans non-coding RNA expression with a combined microarray.

PubMed ID:16738136
Small non-coding RNAs (ncRNAs) are encoded by genes that function at the RNA level, and several hundred ncRNAs have been identified in various organisms. Here we describe an analysis of the small non-coding transcriptome of Caenorhabditis elegans, microRNAs excepted. As a substantial fraction of the ncRNAs is located in introns ... More
