Lyophosome™-Natural Phosphatidylserine (PS) extract catalog is composed of four liposomes made from phosphatidylserine (PS) lipids that are made from natural lipids that are extracted from either brain or soybean. Adding 30% cholesterol makes the liposomes serum stable and is necessary when the liposomes are used in the presence of serum.
These liposomes are all anionic due to the negative charge of phosphatidylserine.
Brain phosphatidylserine (PS) is composed of both saturated and unsaturated lipids. Brain PS contains much larger percentage of saturated lipids compare to Soy PS. Brain PS is mainly composed of four lipids: 42% of 18:0 lipid, 30% of 18:1 lipid, 2% of 20:4 lipid and 11% of 22:6 lipid.
Soy PS is composed of both saturated and unsaturated lipids. Soy PS contains more unsaturated lipids. Soy PC is mainly composed of 5 lipids: 10% of 16:0 lipid, 3% of 18:0 lipid, 12% of 18:1 lipid, 68% of 18:2 lipid, and 7% of 18:3 lipid.
Lyophosome™ product catalog is composed of a large selection of freeze-dried liposomes with various types of lipids and wide range of zeta potentials and different properties. Lyophosome™ products should be used by scientists who understand liposome formulation and have the proper equipment to check the size, separate non-encapsulated drugs and do the proper assays. Freeze-dried liposomes cannot be used blindly.

我想用酶联免疫斑点（ELISPOT）技术测定NK细胞活性，但不知道哪里能买到试剂盒，特向大家求助，谢谢。
尤其是获得SCI文献引用的产品，
绝对ok的
请问一般的实验室可以进行ELIspot吗？（我可以买到现成的试剂盒，资金这个应该没有问题。）ELIspot的难点在哪里？多谢大虾们的指点！这个对我很重要，多谢！！！
