Description
Technical field
The invention belongs to technical field of biological materials, in particular it relates to a kind of method that fish skin collagen is self-assembled into fiber.
Background technology
Collagen is the class formation albumen in animal tissue, accounts for the 1/3 of total protein concentration, is distributed widely in the skin of animal
The positions such as skin, bone, cartilage, connective tissue, tendon, cornea, gut cell interstitial, flesh chamber, ligament, sclera.Because it has uniqueness
Triple helix structure, low antigenicity, nontoxicity, good biocompatibility and the features such as biodegradability, it is extensive
Cured applied to the biology such as tissue engineering bracket material, styptic sponge, medicine control slow-released system, gene delivery vector, aesthetic surgery
Use field.But, the collagen used at present is mainly derived from pigskin, ox-hide and pig bone, ox bone, in recent years due to crazy ox
People and animals' cross-current such as disease, aftosa row is sick to be taken place frequently, and the application for the collagen originated in pig and ox is restricted.In addition,
In some religion crowds, the collagen in pig source is prohibited from using.In this case, aquatic collagen protein is due to raw material
Enrich, be easy to extraction, low antigenicity, low irritability, highly soluble, without infectious disease is dangerous and religion obstacle and by extensive
Concern.Wherein deep-sea fish skin collagen, as the term suggests it is exactly the collagen extracted by raw material of deep-sea fish fish-skin.Due to
The low-temp low-pressure at deep-sea, makes this kind of collagen have common terrestrial animal collagen and fresh-water fishes, shallow sea collagen
Special nature not available for albumen.Difference is the temperature of collagen activity excitation first.The glue extracted in terrestrial animal
Former protein active could will all be excited at 35 degree active.That is the effect that absorbed more than 35 degree can just reach most
It is good.And the activity excitation temperature that fish is extracted will be much lower, more than ten degree just can play best effect.
Self assembly is the key property of collagen.Generally, the collagen being dissolved in solution is free polypeptide chain, rather than
Triple helix chain.Collagen can form triple helix structure by self assembly, and then form fiber etc., and this is it in biomaterial
The basis of field application.Terrestrial mammal collagen is directed to the conventional research on collagen assembly more, it is collagenogenic to water
Inquire into less.
