Extraction of Entamoeba histolytica membrane proteins using three extraction methods

ABSTRACT: Entamoeba histolytica membrane proteins are important players in the parasite’s pathogenicity. However, most of the proteins have not been identified. This study reports the membrane proteins extracted using three extractions methods: two commercial kits (ProteoExtract® from Calbiochem and ProteoPrep® from Sigma), and a conventional laboratory method. The resulting membrane fractions (MF) and cytosolic fractions (CF)were analysed using LC-ESI-MS/MS. The proteins identified in at least two out of three biological replicates revealed a total of 490, 492, and 587 MF proteins extracted using the ProteoExtract® kit, ProteoPrep® kit and conventional method, respectively. Meanwhile, 487, 611 and 343 proteins were identified in the CF extracted using the ProteoExtract® kit, ProteoPrep® kit and conventional method, respectively. Analysis of the identified MF and CF proteins extracted by the respective extraction kits suggests that the ProteoPrep® extraction kit was the most selective in separating MF and CF among the three extraction methods.

Entamoeba histolytica membrane proteins are important players toward the pathogenesis of amoebiasis, but the roles of most of the proteins are not fully understood. Since efficient protein extraction method is crucial for a successful MS analysis, three extractions methods are evaluated for the use in studying the membrane proteome of E. histolytica: Two commercial kits (ProteoExtract from Calbiochem and ProteoPrep from Sigma), and a conventional laboratory method. The results show that ProteoEx ...[more]

Project description:We tested four gene enrichment and complexity reduction target preparation methods for scoring SFPs on the Affymetrix GeneChip 18k Maize Genome Array (âMaize GeneChipâ). Methylation filtration (MF), Cot filtration (CF), mRNA-derived cRNA, and amplified fragment length polymorphism (AFLP) methods were applied to three diverse maize inbred lines (B73, Mo17, and CML69) with three replications per line (36 Maize GeneChips). Due to large amounts of repetitive, mobile DNA, the maize genome requires a target preparation method that offers both a high level of gene enrichment and accurate scoring of SFPs. The objectives of this research are (i) to determine which target preparation method (CF, MF, mRNA, or AFLP) optimally enriches for gene sequences complementary to probe sequences on the Affymetrix GeneChip Maize Genome Array and (ii) to estimate SFP detection power for each target method. The AFLP technology is covered by patents, and patent applications owned by Keygene N.V. AFLP is a registered trademark of Keygene N.V. GeneChip.
