Protein Enrichment through serum IgG removal

The BioMag® ProMax Serum IgG Removal Kit is based on patented BioMag® superparamagnetic particle technology. BioMag® ProMax IgG Removal Particles, in combination with specific buffer conditions, bind the IgG from the serum enabling it to be depleted from the sample. Using magnetically responsive particles for depletion of IgG has advantages over other systems. Removal of IgG with the BioMag® ProMax Serum IgG Removal Kit is a rapid and simple procedure that requires no pretreatment of the sample. In addition, the ProMax system does not require the use of time consuming columns or centrifugation. The ProMax protocol is scalable and can be used in conjunction with the BioMag®ProMax Albumin Removal Kit (Cat. #24351-1).

BioMag® ProMax Serum IgG Removal Kit is supplied with particles and buffers for carrying out 10 separation reactions.

转染技术新宠-Polysciences阳离子聚合物基因转染技术 其优点：适用宿主广泛，操作简便，细胞毒性小，转染率高。其中聚乙烯亚胺（PEI）的转染性能最好。聚乙烯亚胺是一种具有较高的阳离子电荷密度的有机大分子，每相隔两个碳原子，就是第三个原子都是质子化的氨基氮原子，使得聚合物网络在任何PH下都能充当有效的“质子海绵”体。这种聚阳离子能将各种报告基因转入各种种属细胞，其效果好于脂质聚酰胺，而且细胞毒性低。大量实验证明，PEI是非常有希望的基因治疗载体。目前在设计更复杂的基因载体时，PEI经常做为核心组成成分。
