Phage Display Library Construction Phage display is a powerful technique used to study protein-protein, protein-peptide, and protein-DNA interactions. It involves displaying a peptide or protein of interest on the surface of a bacteriophage by fusing the gene encoding the peptide or protein with a gene encoding one of the phage coat proteins. The constructed phage display library can be used to identify high-affinity binding partners. Here is a typical protocol for constructing a phage display library. https://lnkd.in/g63sJNhb #PhageDisplay #LibraryConstruction #ProteinInteractions #PeptideLibrary #Bacteriophage #ProteinBinding #MolecularBiology #GeneticEngineering #AffinitySelection #BiotechResearch #ScientificProtocols #ProteinDesign #NanobodyDiscovery #HighAffinityBinders #AlphaLifetech

Latest News|News-Medicial|Aug 23 2024-Alpha Lifetech Friday News In a recent study published in the New England Journal of Medicine, researchers discussed a comparison of the efficacy of risakizumab and ustekinumab in treating moderate to severe Crohn's disease. Risankizumab appears to be more effective than ustekinumab in clinical and endoscopic remission in patients with moderate to severe Crohn's disease. The higher efficacy of risankizumab may be attributed to its increased affinity for IL-23, superior ability to inhibit IL-23, or the role of IL-12 in protecting the intestinal microenvironment from inflammation. Regarding safety, research results indicate that both risankizumab and ustekinumab have acceptable side effects. https://lnkd.in/gKKMcSjh https://lnkd.in/gFCJPj7d #Risankizumab #Ustekinumab #CrohnsDisease #InflammatoryBowelDisease #IBDResearch #ClinicalTrials #EfficacyStudy #NewEnglandJournalOfMedicine #EndoscopicRemission #MedicalNews #HealthcareInnovation #AlphaLifetech

Nanobody Phage Display Library A Nanobody Phage Display Library is a collection of genetic sequences encoding nanobodies (singledomain antibodies), displayed on the surface of bacteriophages. This library enables the rapid identification and isolation of nanobodies that bind specifically to a wide range of target molecules. Nanobody phage display technology combines the advantages of nanobodies with the powerful phage display selection system, making it a valuable tool in research, diagnostics, and therapeutic development. https://lnkd.in/gP5D8Rfm #Nanobody #PhageDisplay #AntibodyDiscovery #DrugDevelopment #NanobodyEngineering #AlphaLifetech

fab and fc region of the antibody Fab Region (Fragment, antigen-binding) Structure: The Fab region consists of the variable domains of both the heavy and light chains of the antibody. Each antibody has two Fab regions, one on each arm of the Y-shaped structure. Fc Region (Fragment) Structure: The Fc region is located in the stem of the Y-shaped antibody, formed by the constant regions of the heavy chains (CH2 and CH3). It is common to all antibodies of the same isotype (IgG, IgM, IgA, IgE, and IgD). https://lnkd.in/g63sJNhb #AntibodyStructure #FabRegion #FcRegion #NanobodyDiscovery #VaccineDevelopment #TherapeuticAntibodies #AutoimmunityResearch #DiagnosticTools #CellularImmunity #AntibodyEngineering #Alphalifetech

High-throughput screening High-throughput screening (HTS) is a method used in drug discovery and other fields to rapidly test large numbers of compounds, genes, or other substances to identify those that have a desired effect or activity. This technique allows researchers to efficiently sift through many samples to find potential candidates for further investigation. https://lnkd.in/gFCJPj7d #HighThroughputScreening #DrugDiscovery #HTS #PharmaceuticalResearch #BiotechInnovation #CompoundScreening #RapidTesting #GeneticScreening #LeadDiscovery #AssayDevelopment #MolecularBiology #Alphalifetech

Latest News|News-Medicial|Aug 7 2024-Alpha Lifetech Wednesday News Acute lymphoblastic leukemia (ALL) impacts both children and adults, but children have a higher likelihood of being cured, with long-term survival rates exceeding 85%, compared to 50-75% in adults. Researchers at St. Jude Children's Research Hospital conducted an extensive study to uncover the biological reasons behind this disparity. Their findings, published today in the Journal of Clinical Oncology, offer a detailed blueprint for understanding B-cell acute lymphoblastic leukemia (B-ALL), the most prevalent form of the disease. https://lnkd.in/gFCJPj7d https://lnkd.in/g_qsZ7wR #AcuteLymphoblasticLeukemia #ALLResearch #CancerAwareness #BCellLeukemia #ChildhoodCancer #AdultLeukemia #CancerSurvivorship #newsmedicial #AlphaLifetech

Advantages of Phage Display Phage display is a powerful and versatile technology used to study protein interactions, identify binding partners, and engineer novel proteins and antibodies.

affinity tag protein purification Purification Process 1. Cloning and Expression Gene Fusion: The gene encoding the protein of interest is fused with the DNA sequence encoding the affinity tag. Expression Vector: The fusion construct is inserted into an appropriate expression vector. Host Cells: The vector is introduced into host cells (e.g., E. coli, yeast, mammalian cells) to express the tagged protein. 2. Cell Lysis Lysis Method: Cells are lysed using mechanical disruption, sonication, or chemical lysis to release the proteins. Buffer: Lysis buffer typically contains protease inhibitors to prevent protein degradation. 3. Binding to Resin Loading: The cell lysate is loaded onto a chromatography column containing the ligand specific for the affinity tag. Binding Conditions: Conditions are optimized to ensure the tagged protein binds efficiently to the resin. 4. Washing Wash Buffer: The column is washed with buffer to remove non-specifically bound proteins and impurities. Stringency: Wash conditions may vary in stringency depending on the tag and the desired purity level. 5. Elution Elution Buffer: The bound protein is eluted using a buffer that disrupts the interaction between the tag and the resin (e.g., imidazole for His-tag, glutathione for GST-tag). Fractions: Eluted fractions are collected and analyzed. 6. Tag Removal (Optional) Protease Cleavage: Some tags can be removed by specific proteases if necessary for downstream applications. Protease Sites: Cleavage sites are included between the tag and the protein during the cloning step. https://lnkd.in/gFCJPj7d #AffinityTag #ProteinPurification #GeneCloning #ProteinExpression #ExpressionVector #FusionConstruct #HostCells #Ecoli #Yeast #MammalianCells #CellLysis #LysisMethods #ProteaseInhibitors #ChromatographyColumn #BindingResin #ProteinBinding #WashBuffer #NonSpecificBinding #ImpurityRemoval #OptimizedConditions #AffinityChromatography #Biotech #LaboratoryTechniques #ResearchScience #ProteinIsolation #Biopharma #MolecularBiology #ScientificResearch #Alphalifetech #ProteinTags
