  1. 1. How much can the cross-linking of chromatographic media affect the porosity?

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Carl Östling; [2022]
    Nyckelord :Liquid chromatography; Size exclusion chromatography; Agar; Chromatographic resins; Distribution coefficient; Vätskekromatografi; Storleksuteslutningskromatografi; Agar; Stationär fas; Fördelningskoefficient;

    Sammanfattning : Vätskekromatografi är vanligt förekommande metod för separationer av molekyler inom bioteknik. Det finns inom begreppet vätskekromatografi många olika tekniker och vilken specifik teknik som är mest lämplig för en given separation beror på egenskaperna hos den avsedda målmolekylen. LÄS MER

  3. 2. Role of PARN gene in telomere maintenance in a zebrafish model

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Spandana Tharanath Kotian; [2021]
    Nyckelord :;

    Sammanfattning : The telomeres are highly conserved repetitive DNA sequence elements present at the ends of linear chromosome. These structures function as a biological clock of the cell since telomeres become shorter with each replication cycle and finally reach a critical threshold in their length after which the cell enters senescence.

  4. 3. Integration of Modelling Environments to an ÄKTA System

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Linus Gustafsson; Daniel Nilsson; [2018]

    Sammanfattning : Automated information flow is an important way of optimizing the time used for analyzing processes. Other added benefits are that in a well-made automated system, the probability of human error diminishes because less liability is put on the person to manually transport and utilize the data.

  5. 4. Model Calibration and Optimization of a Protein Purification Process

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sadiq Al-Kaisy; [2015]
    Nyckelord :Model calibration; Protein purification; Ion-exchange chromatography; Optimization; chemical engineering; kemiteknik; Chemistry; Technology and Engineering;

    Sammanfattning : Four different chromatography models were calibrated to describe the separation of a ternary protein mixture consisting of lysozyme, cytochrome C and ribonuclease A in an ion-exchange chromatography column. The models are based on the same column model, the kinetic dispersive model. LÄS MER

  7. 5. Determining the oligomeric structure of PARN

    Master-uppsats, Institutionen för cell- och molekylärbiologi

    Författare :Mikael Nissbeck; [2012]
    Nyckelord :Poly A -specific ribonuclease PARN ; deadenylation; mRNA metabolism; cap stimulation; oligomerization;

    Sammanfattning : Poly(A)-specific ribonuclease (PARN) is a deadenylase that degrades the poly(A) tail of eukaryotic mRNA. PARN also interacts with the 5’-cap structure of the mRNA. The binding of the cap structure enhances the deadenylation rate. PARN has previously been described as a dimer. LÄS MER
