Problems solved by technology

[0013] Studies have shown that cells can be stably passaged in serum-free medium for a long time. However, the serum-free medium currently studied mainly shows that the applicable spectrum of cells is extremely narrow, and cells are more susceptible to certain mechanical and chemical factors in serum-free medium. Influence, storage and application of medium are not as convenient as traditional synthetic medium

Embodiment 1

[0021] The present invention consists of recombinant human insulin-like growth factor-1: 0.1gL (concentration), recombinant human platelet-derived growth factor-B: 0.3g / L, recombinant human basic fibroblast growth factor: 0.2g / L, bovine transfection Ferritin: 3g / L, bovine serum albumin (V component): 6g / L, mercaptoethanol: 0.5mol / L.

Embodiment 2

[0023] The present invention consists of recombinant human insulin-like growth factor-1: 0.5g / L (concentration), recombinant human platelet-derived growth factor-B: 0.1g / L, recombinant human basic fibroblast growth factor: 0.1g / L, Bovine transferrin: 2g / L, bovine serum albumin (component V): 8g / L, mercaptoethanol: 0.4mol / L.

Embodiment 3

[0025] The present invention consists of recombinant human insulin-like growth factor-1: 0.3g / L (concentration), recombinant human platelet-derived growth factor-B: 0.4g / L, recombinant human basic fibroblast growth factor: 0.3g / L, Bovine transferrin: 4g / L, bovine serum albumin (component V): 12g / L, mercaptoethanol: 0.3mol / L.

[0026] Preparation method:

[0027] First, prepare a basal medium consistent with cell culture, such as RPMI1640 or DMEM or F12 or DMEM / F12, etc., the concentration of which is 4 times the normal concentration, and sterilize and filter with a 0.2 μm filter membrane;

[0028] Use the above basic medium to dissolve the weighed bovine transferrin and bovine serum albumin respectively, and filter them with a 0.2 μm filter membrane to sterilize;

[0029] Mix the sterilized solution of bovine transferrin and bovine serum albumin under slow stirring, add mercaptoethanol in proportion, and then add the calculated volumes of recombinant human insulin-like growth...

Abstract

The invention relates to a non-serum animal cell culture used fetus cattle serum displace agent, which is formed by recombination human insulin growth factor-1:0.1g-0.5g / l, recombination human platelet sourced growth factor-B:0.1g-0.6g / l, recombination human alkali desmocyte growth factor: 0.05-0.4g / l, cattle transferring: 1g-5g / l, cattle serum protein (V component): 2g-15g / l, and mercaptoethanol 0.3-0.5mol / l.

Description

technical field [0001] The invention relates to a serum-free formula fetal bovine serum substitute for animal cell culture, in particular to a fetal bovine serum substitute (serum-free formula) for animal cell culture that can be matched with various basal media. Background technique [0002] The in vitro culture of animal cells mostly uses serum-containing medium for culture, which is costly, the serum composition is not clear, and it is not easy to purify downstream products. More importantly, the serum contains potential viruses (such as mad cow virus, etc.), prion or mycoplasma contamination The biological effects of serum supporting cell growth have been proven, but the complex components in serum have not yet been fully understood. There are not only cell growth-promoting factors in serum, but also cell growth-inhibiting factors or toxic factors in the same pair, so The biological characteristics reflected by cells cultured in serum-containing medium are the comprehens...
