多肽H2N-Tyr-Ala-Pro-Gly-Thr-Phe-Ile-Ser-Asp-Tyr-Ser-Ile-Ala-Met-Asp-Lys-Ile-His-Gln-Gln-Asp-Phe-Val-Asn-Trp-Leu-Leu-Ala-Gln-Lys-Gly-Lys-Lys-Asn-Asp-Trp-Lys-His-Asn-Ile-Thr-Gln-COOH的合成步骤：
1、合成CTC树脂：称取0.58g CTC Resin（如初始取代度约为0.92mmol/g）和0.64mmol Fmoc-Gln(Trt)-OH于反应器中，加入适量DCM溶解氨基酸（需要注意，此时CTC树脂体积会增大好几倍，避免DCM溶液过少），再加入1.6mmol DIPEA（Mw：129.1,d：0.740g/ml），反应2-3小时后，可不抽滤溶液，直接加入1ml的HPLC级甲醇，封端半小时。依次用DMF洗涤2次，甲醇洗涤1次，DCM洗涤一次，甲醇洗涤一次，DCM洗涤一次，DMF洗涤2次（这里使用甲醇和DCM交替洗涤，是为了更好地去除其他溶质，有利于后续反应）。得到 Fmoc-Gln(Trt)-CTC Resin。结构图如下：
2、脱Fmoc：加3倍树脂体积的20%Pip/DMF溶液，鼓氮气30分钟，然后2倍树脂体积的DMF 洗涤5次。得到 H2N-Gln(Trt)-CTC Resin 。（此步骤脱除Fmoc基团，茚三酮检测为蓝色，Pip为哌啶）。结构图如下：
3、缩合：取1.6mmol Fmoc-Thr(tBu)-OH 氨基酸，加入到上述树脂里，加适当DMF溶解氨基酸，再依次加入3.2mmol DIPEA，1.52mmol HBTU。反应30分钟后，取小样洗涤，茚三酮检测为无色。用2倍树脂体积的DMF 洗涤3次树脂。（洗涤树脂，去掉残留溶剂，为下一步反应做准备）。得到Fmoc-Thr(tBu)-Gln(Trt)-CTC Resin。氨基酸：DIPEA：HBTU：树脂=3：6：2.85：1（摩尔比）。结构图如下：
4、依次循环步骤二、步骤三，依次得到

以上中间结构，均可在专肽生物多肽计算器-多肽结构计算器中，一键画出。
最后再经过步骤二得到 H2N-Tyr(tBu)-Ala-Pro-Gly-Thr(tBu)-Phe-Ile-Ser(tBu)-Asp(OtBu)-Tyr(tBu)-Ser(tBu)-Ile-Ala-Met-Asp(OtBu)-Lys(Boc)-Ile-His(Trt)-Gln(Trt)-Gln(Trt)-Asp(OtBu)-Phe-Val-Asn(Trt)-Trp(Boc)-Leu-Leu-Ala-Gln(Trt)-Lys(Boc)-Gly-Lys(Boc)-Lys(Boc)-Asn(Trt)-Asp(OtBu)-Trp(Boc)-Lys(Boc)-His(Trt)-Asn(Trt)-Ile-Thr(tBu)-Gln(Trt)-CTC Resin，结构如下：
5、切割：6倍树脂体积的切割液（或每1g树脂加8ml左右的切割液），摇床摇晃 2小时，过滤掉树脂，用冰无水乙醚沉淀滤液，并用冰无水乙醚洗涤沉淀物3次，最后将沉淀物放真空干燥釜中，常温干燥24小试，得到粗品H2N-Tyr-Ala-Pro-Gly-Thr-Phe-Ile-Ser-Asp-Tyr-Ser-Ile-Ala-Met-Asp-Lys-Ile-His-Gln-Gln-Asp-Phe-Val-Asn-Trp-Leu-Leu-Ala-Gln-Lys-Gly-Lys-Lys-Asn-Asp-Trp-Lys-His-Asn-Ile-Thr-Gln-COOH。结构图见产品结构图。
切割液选择：1）TFA：H2O=95%：5%
2）TFA：H2O：TIS=95%：2.5%：2.5%
3）三氟乙酸：茴香硫醚：1，2-乙二硫醇：苯酚：水=87.5%：5%：2.5%：2.5%：2.5%
（前两种适合没有容易氧化的氨基酸，例如Trp、Cys、Met。第三种适合几乎所有的序列。）
6、纯化冻干：使用液相色谱纯化，收集目标峰液体，进行冻干，获得蓬松的粉末状固体多肽。不过这时要取小样复测下纯度 是否目标纯度。
7、最后总结：
