MK-2894 is a highly potent and selective inhibitor of EP4 receptor with IC50 value of 2.5 nM [1].
MK-2894 is a highly selective and potent second generation EP4 antagonist with a Ki of 0.56±0.1nM in the radio ligand binding assay using membranes prepared from human EP1-4 overexpressed HEK 293 cell lines. And the EP4 functional assay measures the inhibition of PGE2-induced cAMP accumulation with IC50 of 2.5±0.7nM. In the AIA model and GI tolerability model in male SD rats, MK-2894 shows a dose-dependent inhibition of pain response with ED50 of 0.36 mg/kg. It also has the potent activity in inhibiting chronic pawswelling with ED50 of 0.02 mg/kg/day. Overall, MK-2894 displays the desired potency, selectivity, pharmacokinetic, and GI tolerability profile for further development and represents a potential safer alternative for treating pain and inflammation than traditional NSAIDs and coxibs [1].

问:1如才能提高柱子吸附蛋白量?
2样品中的核酸对吸附有无太大影响?
3我拟采用阴离子交换树脂,问pH8.0条件下除去核酸可否?
4怎么提高样品的澄清度?
另外还想问一下,还有其他可行的破碎方法吗
谢谢
我怀疑溶菌酶有问题,因为其消化的30min内菌液几乎没大变化,而我曾看到别人用溶菌酶消化时菌液变的挺粘稠。
今下午再做时还是没什么变化,但发现溶菌酶在冰上静置2-3h后竟然沉淀下来了,而且上清和下面的白色溶菌酶分界明显,是我的溶菌酶配的有问题吗?出现这种情况溶菌酶还能用吗?我是-20度保存的。
下一步怎么处理菌液呢?
请高手多多指教!
大家请赐教!
