For training students, a laboratory course based on the production of marker proteins is proposed. Following fractionation by column chromatography, a series of purified proteins and mixtures of proteins were combined to generate various sets of unstained, prestained and fluorescently labeled molecular weight ladders for SDS‐PAGE. The produced material can be used in successive laboratory practices as an alternative to commercial protein markers.</jats:p>","journal":"Biochemistry and Molecular Biology Education","year":2021,"id":38138,"datarank":0.22091388257587102,"base_score":1.3862943611198906,"endowment":1.3862943611198906,"self_citation_contribution":0.20794415416798362,"citation_network_contribution":0.012969728407887404,"self_endowment_contribution":0.20794415416798362,"citer_contribution":0.012969728407887404,"corpus_percentile":null,"corpus_rank":null,"citation_count":3,"citer_count":2,"citers_with_citation_signal":1,"citers_with_endowment":1,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":189698,"name":"José Bubis","orcid":"0000-0002-8839-6745","position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":1.3862943611198906,"endowment":1.3862943611198906,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"33301651","pmcid":null,"openalex_id":"https://openalex.org/W3110867787","authors":[],"funders":[],"total_grants":0,"fwci":0.0,"citation_percentile":0.13924151,"influential_citations":0,"citation_trend":[{"year":2024,"count":1},{"year":2025,"count":2}],"oa_status":"closed","license":"http://onlinelibrary.wiley.com/termsAndConditions#vor","oa_locations":[{"url":"https://onlinelibrary.wiley.com/doi/pdf/10.1002/bmb.21476","host_type":"publisher"},{"url":"https://onlinelibrary.wiley.com/doi/full-xml/10.1002/bmb.21476","host_type":"publisher"},{"url":"https://iubmb.onlinelibrary.wiley.com/doi/pdf/10.1002/bmb.21476","host_type":"publisher"},{"url":"https://doi.org/10.1002/bmb.21476","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/33301651","host_type":"repository"}],"fields_of_study":["Muscle metabolism and nutrition","thermodynamics and calorimetric analyses","Exercise and Physiological Responses","Medicine","Chemistry","Biology","Biomedical Research","Electrophoresis, Polyacrylamide Gel","Humans","Laboratories","Molecular Weight","Proteins"],"mesh_terms":["Electrophoresis, Polyacrylamide Gel","Humans","Laboratories","Molecular Weight","Proteins","Biomedical Research"],"keywords":["Sodium dodecyl sulfate","Polyacrylamide gel electrophoresis","Chromatography","Chemistry","Sodium","Gel electrophoresis","Polyacrylamide","Gel electrophoresis of proteins","Electrophoresis","Biochemistry","Polymer chemistry","Organic chemistry","Column chromatography","Unstained","Sodium Dodecyl Sulfate-polyacrylamide Gel Electrophoresis","Prestained And Fluorescently Labeled Molecular Weight Protein Markers"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-11T00:45:45.416524Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
