Autologous Fibrinogen Purification and Concentration For Use in Fibrin Sealant
… fibrinogen is precipitated from plasma with protamine. The physical properties of fibrin sealant prepared from fibrinogen precipitated with protamine were evaluated. The optimal precipitation conditions included a plasma protamine concentration of 10 mg/mL at room temperature. Under these …

The Effect of Using Bioflocculants as Conditioners on Dewatering of Biosludge
… (Hb), lignin-based flocculants (LBFs), and protamine to enhance the dewaterability.Cationic polymers improve the dewaterability of sludge by neutralizing the negative charge of the biosludge particles. Biopolymers such as hemoglobin and lignin do not possess high charge density naturally. As …

Zur Expression und Funktion von Prm3: ein ungewöhnliches Protamin
… das Prm3-Gen im gleichen Cluster wie die anderen Protamine (Prm1 und Prm2) lokalisiert ist und ausschließlich während der haploiden Phase der Spermatogenese (in den elongierenden Spermatiden) exprimiert wird, wurde es funktionell anfangs der Genfamilie der Protamine zugeordnet. Mittels …

The viability and fertility of bovine spermatozoa encapsulated in microcapsules and microgels
… (100 x 10⁶ sperm/bull) were encapsulated in protamine sulfate microcapsules and simultaneously inseminated with the reciprocal sperm type unencapsulated. Insemination of both sperm types unencapsulated served as a control. Accessory sperm embedded in the zona pellucida were counted and …

Towards A Unified Model Of Sperm Chromatin Structure
… to a transgenic mouse model harboring the human protamine locus, highlighted the potential regulatory impact of the chromatin environment at the local and domain level. Consideration of these results within the context of the endogenous mouse protamine locus identified a candidate transcriptional …

Polymer-coated iron oxide nanoparticles for medical imaging
… by covalently combining Feraheme with protamine, a pharmaceutical that also acts as a membrane translocating agent. A rhodamine-protamine conjugate is synthesized and then covalently bound to amino-FH using carbodiimide (CDI) chemistry. This results in a magnetofluorescent cell-labeling …

The Physiological and Morphological Responses of the Bladder Urothelium to Differential Injury
… UPEC), a cellular damage model from single dose protamine sulfate: SDPS) instillation, and an inflammatory damage model from multiple instillations of lipopolysaccharide: LPS). We identified that UPEC injury increased the pain response to bladder distention while it was decreased by SDPS injury. …

ΦΩΣΦΟΡΥΛΙΩΣΗ ΠΡΩΤΕΙΝΩΝ ΣΕ ΣΥΣΤΗΜΑ ΠΡΩΤΕΙΝΟΣΥΝΘΕΣΗΣ ΕΛΕΥΘΕΡΟ ΚΥΤΤΑΡΩΝ ΑΠΟ ΣΥΚΩΤΙΠΟΝΤΙΚΟΥ. ΚΑΘΑΡΙΣΜΟΣ ΚΑΙ ΧΑΡΑΚΤΗΡΙΣΜΟΣ ΜΙΑΣ ΝΕΑΣ ΚΙΝΑΣΗΣ ΠΡΩΤΕΙΝΩΝ ΠΟΥ ΡΥΘΜΙΖΕΤΑΙ ΑΠΟ ΚΥΚΛΙΚΑ ΝΟΥΚΛΕΟΤΙΔΙΑ
… HISTONES AND POLYSOMAL PROTEINS BUT NOT PROTAMINE, CASEIN OR ANY OF THE PROTEINS OF THE "PH5" FRACTION. AT HIGH (10- 5 M) ATP CONCENTRATIONS MG2+ IS THE MOST EFFICIENT ACTIVATING METAL WHILE AT LOW (10-9 M) ATP CONCENTRATIONS MN2+ IS. THE ACTIVITY OF THE PURIFIED KINASE IS AFFECTED BY THE …

Characterization of the Beta-Karyopherin Protein Ipo9 During Germ Cell Differentiation
… during the transition from histone-based to protamine-based chromatin packaging, import of proteasome components and chromosome segregation during meiosis. Lastly, at the molecular level, we showed that the N-terminal domain, which is critical for nuclear import, is required for Ipo9 function …

Untersuchungen zur regulierbaren transgenen Expression von Ribozymen und „Antisense"-Transkripten mit dem Ziel einer Reduktion der Prm3-Expression
… des evolutionär konservierten Genclusters der Protamine gerichtet. Vor allem die Anwendung der katalytisch aktiven Effektormoleküle (Ribozyme) auf eine mRNA wird erheblich von deren Sekundärstrukturen beeinflußt. Die Aktivität von spezifischen Ribozymen wurde deshalb zunächst in vitro getestet, …

Novel tools for sequence and epitope analysis of glycosaminoglycans
… sensors. Sensors were functionalized either with protamine to quantify total HSGAGs or with antithrombin-III (AT-III) to quantify a specific anticoagulant epitope.

Isolation and characterisation of histone transacetylases
… was shown to be specific for histones with protamine displaced histone complex being the best substrate. Using this histone transacetylase preparation ³H-acetyl total histone was prepared in sufficient yield and with a high enough specific activity to enable sequential Edman degradation of …

A Study of The Effect of Membrane Targeting Antimicrobial Compounds on Ionic Transport Across Lipid Bilayer Membranes
… a chimera of two natural peptides, melittin and protamine. This peptide has a broad spectrum of antibacterial activity against both gram-positive and gram-negative bacteria while having no toxicity in mammalian cells. Melimine was initially synthesised as a coating for contact lenses as a way of …
