BAF312 is a next-generation potent sphingosine 1-phosphate (S1P) receptor agonist, selective for S1P1 (EC50 ~0.39 nM) and S1P5 (EC50 ~0.98 nM). As S1P1 plays a central role in lymphocyte egress from lymph nodes and is a validated drug target in immune-mediated diseases, BAF312 is currently in clinical trials to treat multiple sclerosis.
How to Use:
In vitro: BAF312 was used at 0.1µM in vitro.
In vivo: BAF312 was orally dosed once daily at 0.3-3 mg/kg in chronic EAE, DA rats and was shown good efficacy.

(2)酸和盐浓度等比例也增减时,溶液的pH值不便。
(3)酸和盐浓度相等时,缓冲液的缓冲效率为最高,比例相差越大,缓冲效率越低,一般地说缓冲液有效缓冲范围为PK±1pH
酶提取技术,属地球化学勘查学科。其是由克拉克(J.R.Clark)等人于20世纪80年代末和90年代初研制出的一种利用葡萄糖氧化酶提取矿物颗粒表面的非晶质锰的氧化膜寻找隐伏矿的方法。1995年以后已广泛应用。

甲液:0.05mol/L Na2HPO4溶液 :称取磷酸氢二钠9.465g 7.099g,加蒸 馏水至1000ml ;
乙液:0.05mol/L KH2P04溶液: 称取磷酸二氢钾, 9.07g 6.803g,加蒸馏水至1000m1.
将甲乙液分装在棕色瓶内,于4℃冰箱中保存,用时甲、乙两液各按不同比例混合,即可得所需pH的缓冲液,见下表:
pH 甲液ml 乙液mI
5.29 2.5 97.5
5.59 5.0 95.0
5.91 10.0 90.0
6.24 20.0 80.0
6.47 30.0 70.0
6.64 40.0 60.0
6.81 50.0 50.0
6.98 60.0 40.0
7.17 70.0 30.0
7.38 80.0 20.0
7.73 90.0 10.0
8.04 95.0 5.0
你要配制pH=6.8的PBS,可用甲、乙液各50ml混合即可.
