Serochem PEI转染试剂在CHO悬浮细胞上的转染步骤

Serochem PEI转染试剂在CHO悬浮细胞上的转染步骤

Serochem PEI转染试剂在CHO悬浮细胞上的转染步骤如下:

一、转染前

传代和扩增细胞以获得具有大于95%的活力和介于(1.5至2.0)x 106之间的活细胞密度的培养物.

二、转染

1.在转染前,确保生存能力大于95%,活细胞密度为(1.5至2.0)x 10 6细胞/mL。

2.将活细胞密度稀释至1.05 x 10 6每毫升细胞数。

3.转化pDNA和PEI引物™ 1 mg/mL试剂容器多次以充分混合。

4.将每mL培养物转移1μg pDNA至一个干净的小瓶中转染。用新鲜培养基(5%最终培养体积)稀释至20μg/mL。

5.将5μL PEI Prime转移到一个干净的小瓶中™ 每毫升1毫克/毫待转染的培养物。使用培养基稀释至75μg/mL(5%最终培养物

体积)。

6.将稀释的pDNA和PEI Prime™混合在一起. 反转几次,然后允许在室温下加盖休息10分钟。轻轻翻转,使用前立即关闭容器

一次。

7.使用10mL pDNA/PEI混合物用于每90mL待培养的培养物转染。一边搅拌一边逐渐将混合物加入培养基中。

8.按照典型条件培养细胞。

三、转染后

如果使用饲料、加强剂、补充剂或增强剂,在转染后6小时可以添加

根据细胞培养基的不同,可能需要添加钠丁酸盐添加到培养基中以获得CHO悬浮液中的基因表达。如有必要,确定,制备5个

转染后的亚培养物,并添加丁酸钠至0、2.5、5、7.5或10mM的最终浓度基于最终产率的适当浓度。如果使用GFP对照,转染效率应超过70%。48小时后观察。对于优化的程序,超过80%的效率是合理的。监测表达水平并在

察到稳定滴度后收获。对于典型的过程,在转染后5至7天分泌的蛋白质将最高。其他工艺,如使用低温和/或使用批进料以获得

最大产量,将改变峰值收获窗口。

Gibco™ CD CHO AGT™ Medium

详情介绍

Gibco™ CD CHO AGT™ Medium

The AGT™ dry media format is designed to provide increased consistency and productivity across all stages of production from development to commercial manufacturing. CD CHO AGT™ medium contains no proteins or peptide components of animal, plant, or synthetic origin, as well as no undefined lysates or hydrolysates.


When to Use CD CHO Medium:

• Your GS CHO cells are recommended to be grown in CD CHO medium

• Your cells have been successfully cultured in CD CHO medium in the past and your process is nearing a regulatory filing (DMF available)


When to Consider Another Gibco™ Medium:


Consider CD FortiCHO™ medium when:

• The cell line you are using is a transfected CHO K1, GS CHO or CHO-S™ cell line

• Maximum batch culture cell densities and protein titers are needed

• You have time to adapt cells into a new medium in an effort to maximize titers

• Cell health at harvest is a priority for downstream processing


Consider CD OptiCHO™ medium when:

• You are using a transfected CHO cell line other than CHO K1, GS CHO or CHO-S™ cell lines

• Optimization of feeding strategies will be part of your base medium selection testing in an effort to maximize productivity

• Your CHO cell line is “finicky,” i.e. hard to grow or adapt


Consider CD DG44 medium when:

• You use parental DG44 or DXB11 CHO cells (dhfr-)


Liquid Media Formulations:

Gibco™ AGT™ media are also available in a liquid format that offers the same performance and formulation as the AGT™ media format. Gibco™ liquid media are manufactured animal origin-free with the same complete, serum-free, protein-free, chemically-defined formulation and performance as their AGT™ media counterparts.


Design Your Own Media Specific to Your Needs:

Whether it’s a bench-level experiment or large scale biomanufacturing process, we offer specialized formats, packaging, and quality levels specific to your needs. With Gibco™ cGMP Media Custom Services you can put the manufacturing power and years of technical experience of our R&D and Bioproduction Application Specialists to work for you.

PEG Aldehyde Description:

Aldeyde PEG is an amine reactive PEG derivative that can be used to modify biomolecules via available amine groups. The reaction between aldehyde group with ε-amine of lysine residues and the α-amine at the N-terminus produces an intermediate Schiff base. Further reduction with hydride will form a stable C-N bond. PEG aldehydes react with amine groups at a pH of from 5.5 to 9.5. Higher pH will result in multiple Pegylation with both terminal and lysine groups. Aldehyde PEG is a commonly used PEG reagent for n-terminus pegylation in proteins or peptides.

Physical Properties:

  • Off-white/white solid or viscous liquid depends on molecule weight;
  • Soluble in regular aqeous solution as well as most organic solvents;

Storage Conditions:

  • Store at -20 0C

Reaction Procedures:

Generally, a 10- to 50-fold molar excess of PEG aldehyde over the amount of amine-containing material results in sufficient conjugation.

Materials Required:

  • Pegylation buffer: Amine-free aqueous buffer, pH 6~8.5.
  • PEG aldehyde stock solution: 100 mg in 1 mL conjugation buffer.
  • Washing solution: Distilled water or any aqueous buffer.

Reaction Steps:

Dissolve targeted materials in pegylation buffer. Estimate the concentration of primary amine groups on the targeted materials. Add PEG aldehyde stock solution to the targeted conjugation materials with the final concentration keep at least 10 mg/mL. Allow mixture agitates at room temperature for 2~4 hrs at room temperature or overnight 4 0C. After reaction, C=N bond can be reduced by sodium borohydride. Conjugate can be purified either by size exclusion chromatography or dialysis.

  • Soluble in regular aqeous solution as well as most organic solvents;

Storage Conditions:

  • Store at -20 0C

Reaction Procedures:

Generally, a 10- to 50-fold molar excess of PEG aldehyde over the amount of amine-containing material results in sufficient conjugation.

Materials Required:

  • Pegylation buffer: Amine-free aqueous buffer, pH 6~8.5.
  • PEG aldehyde stock solution: 100 mg in 1 mL conjugation buffer.
  • Washing solution: Distilled water or any aqueous buffer.

Reaction Steps:

Dissolve targeted materials in pegylation buffer. Estimate the concentration of primary amine groups on the targeted materials. Add PEG aldehyde stock solution to the targeted conjugation materials with the final concentration keep at least 10 mg/mL. Allow mixture agitates at room temperature for 2~4 hrs at room temperature or overnight 4 0C. After reaction, C=N bond can be reduced by sodium borohydride. Conjugate can be purified either by size exclusion chromatography or dialysis.

Description:

DSPE PEG aldehyde (DSPE-PEG-CHO) is one of Nanocs’ reactive phospholipid PEG derivatives that can react with N-terminus amine groups. DSPE (1,2-distearoyl-sn-glycero-3-phosphoethanolamine) is an 18 carbon phospholipid that is highly hydrophobic. PEG backbone, on the other hand, offers good hydrophilicity. Aldehyde PEG DSPE is a reactive lipid PEG with good reactivity towards amine, oxyamine or hydrazide groups. Aldehyde reacts with N-terminus amine groups to form an intermediate Schiff base. Further reduction with hydride will form a stable C-N bond. Aldehyde PEG DSPE allows conjugation of DSPE PEG to amine or hydrazide group at acidic conditions with good selectivity. Higher pH will result in multiple pegylation with amine groups.
