PODS® Human GDNF (Glial cell derived neurotrophic factor, 胶质细胞源性神经营养因子)

PODS® Human GDNF

PODS® co-crystals	PODS® co-crystals

PODS 技术

将生长因子包埋进蛋白质晶体（多角体蛋白）中，多角体蛋白能够保护包埋的生长因子，并维持其稳定性与生物活性，进而持续释放到细胞培养系统中。

PODS GDNF 描述

PODS多角体蛋白与GDNF共结晶。GDNF (Glial cell derived neurotrophic factor，胶质细胞源性神经营养因子)是由Lin等(1993)从鼠胶质细胞株B49的条件培养基中分离纯化获得的一种神经营养因子，且由此而命名。以纯化的GDNF的氨基端序列制作探针，克隆得到大鼠和人的GDNF基因。人GDNF前体蛋白为211个氨基酸残基(其中信号肽19个氨基酸)，加工处理后才形成分泌型的成熟蛋白，有134个氨基酸，是一个糖基化的二硫键连结的同源二聚体蛋白质，分子量为32~34kD，为碱性蛋白质。

The product contains the polyhedrin protein co-crystalized with Human GDNF. Glial cell-derived neurotrophic factor (GDNF) is a neurotrophic factor that signals through a multicomponent receptor system to activate receptor tyrosine kinase RET signaling. GDNF promotes dopamine uptake, prevents motor neuron apoptosis, and supports the survival and differentiation of neurons.

PODS GDNF 使用建议

PODS® co-crystals provide a depot of proteins which are steadily secreted. It has been estimated that the biological activity of 50 million PODS® co-crystals generates the same peak dose as 3.3 μg of standard recombinant protein. However, at 5 days following the start of seeding the PODS® co-crystals, there are more than 50% of these peak levels still present in the culture system. Ultimately, the amount of PODS® co-crystals that is optimal for a particular experiment should be determined empirically. Based on previous data, we suggest using 50 million PODS® co-crystals in place of 3.3 μg of standard growth factor as a starting point."

To control for cross-reactivity with cells or as a negative control, we recommend using PODS® growth factors alongside PODS® Empty crystals, as the latter do not contain or release cargo protein.
