Abstract

the invention discloses a non-serum substratum for cell of HEK 293, which is composed of transferring, insulin, Primatone, lipoid compound, amino acid, inorganic salt and vitamin based on basic substratum.

Description

Human embryo kidney (HEK) 293 cell non-serum culture mediums
Technical field
The present invention relates to a kind of substratum that is used for human embryo kidney (HEK) 293 cell cultures, specifically, relate to a kind of serum free medium of the HEK293 of being used for cell cultures.
Background technology
Human embryo kidney (HEK) 293 cells are at first set up in 1977 by Graham etc., are the desirable hosts who produces recombinant adenovirus.
Traditional substratum of HEK293 cell is that blood serum medium is arranged.But, there is the use of blood serum medium to be restricted along with people improve constantly the understanding that animal serum may pollute production process even the finished product.Serum free medium, with its have passivity pollute, batch between otherness advantages such as separation and purification little and that help expression product more and more be subjected to people's attention.
The existing at present serum free medium that is fit to the HEK293 cell cultures has: 293-SFMII (Invitrogen), Ex-Cell 525 (JRH), IS293-SF (Irvine Scientific), Pro293s-CDM (Cambrex), CD293 Medium, Freestyle TM293 and Expression Medium (Gibco) etc., but the price comparison costliness of these serum free mediums.Therefore this area presses for the serum free medium of a kind of low cost of research and development and suitable HEK293 cell cultures.
Summary of the invention
The object of the invention is, a kind of low cost is provided and has been applicable to the serum free medium of human embryo kidney (HEK) 293 cell cultures.
Design of the present invention is such:
In the serum free medium owing to lack serum, the essential blood serum substituting factor of adding, current, the recruitment factor kind of alternative serum has a lot, generally includes somatomedin, hormone, lipid, conjugated protein and trace element etc.In order to develop the serum free medium that is fit to the HEK293 cell, the present invention has added following serum substitute:
(1) Transferrins,iron complexes: a kind of glycoprotein in conjunction with iron, with the single-minded receptor acting of cell surface, transmit iron ion.
(2) Regular Insulin: beta Cell of islet excretory polypeptide hormone, promote the cell growth, regulate the metabolism of glucose and lipid.
(3) Primatone: a kind of peptone, can play stable and the active function of adjusting above-mentioned substance in anteserum-less substrate by combining with VITAMIN, lipid, metal ion, hormone and somatomedin.In the stir culture system, the mechanicalness protection effect that viscosity by influencing substratum and oncotic pressure are brought into play pair cell.
(4) lipid mixture: phosphatide is the integral part of cell, adds lipid mixture and can promote the synthetic of phosphatide, accelerates the synthetic of cytolemma, increases the slipperiness of cytolemma.
Because lack the effect of serum, corresponding variation can take place the metabolism situation of cell when serum-free culture, nutritional needs is corresponding to change, and for this reason, changes the content of composition on the basis of the nutritive ingredient of basic medium that must be when having serum to cultivate.Amino acid is the precursor of protein synthesis, and its utilization is also grown for cell and product production provides energy.Amino acid can also be alleviated the influence of generation, carbonic acid gas and the osmotic pressure of ammonia.The production of adenovirus has bigger demand to amino acid, and therefore, HEK293 cell non-serum culture medium of the present invention contains than the more amino acid of general basic medium.
