Salmon thrombin (三文鱼凝血酶/鲑鱼凝血酶)
Catalog Number
SEA-135Description
Plasma protein from the blood of farmed S. salarProduct Background
Background:- Fibrin gels made from salmon proteins have demonstrated remarkable properties in neuron survival and growth.
- Salmon fibrin gels represent the optimal matrix for neuronal cell cultural
- Salmon fibrin gels have also properties superior to mammalian gels in an in vitro angiogenesis model. The salmon gels were 60-188% more efficient than human fibrin gels supporting growth of human endothetlial cells. These results indicate that salmon fibrin may be attractive alternate ECM for support of microvascular network formation.
- Salmon fibrinogen and thrombin can be used at room temperature
- Soft salmon fibrin gels have been shown to promote selection and growth of tumorigenic cells
Research Targets:
- Regenerative Medicine
- Spinal Cord Injury
- Neural cell regrowth
- Pain & CNS Investigators
- Stem Cell Research
- Cancer stem cell research
Benefits:
- Superior Performance- demonstrated superiority to Matrigel as an extracellular matrix for neuronal cell growth.
- Safety from mammalian pathogens
- Easy of rehydration & improved thermal properties.
