This fragment of the coagulation factor XIIIa inhibits cross-linking by the factor XIIIa (IC₅₀ = 52 µM), as well as fibrinogen α-chain cross-linking by the guinea pig liver tissue transglutaminase (IC₅₀ = 13 µM).
Coagulation Factor XIIIa (190-230)是凝血因子XIIIa的一个片段多肽，它可以抑制因子XIIIa的交联(IC50 = 52 µM)，也可以抑制豚鼠肝脏组织谷氨酰胺转胺酶凝血因子I α-的交联(IC50 = 13 µM)。

多肽H2N-Asp-Asp-Ala-Val-Tyr-Leu-Asp-Asn-Glu-Lys-Glu-Arg-Glu-Glu-Tyr-Val-Leu-Asn-Asp-Ile-Gly-Val-Ile-Phe-Tyr-Gly-Glu-Val-Asn-Asp-Ile-Lys-Thr-Arg-Ser-Trp-Ser-Tyr-Gly-Gln-Phe-COOH的合成步骤：
1、合成CTC树脂：称取0.35g CTC Resin（如初始取代度约为0.4mmol/g）和0.17mmol Fmoc-Phe-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0.42mmol 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-Phe-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-Phe-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0.42mmol Fmoc-Gln(Trt)-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0.84mmol DIPEA，0.4mmol 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-Gln(Trt)-Phe-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-Asp(OtBu)-Asp(OtBu)-Ala-Val-Tyr(tBu)-Leu-Asp(OtBu)-Asn(Trt)-Glu(OtBu)-Lys(Boc)-Glu(OtBu)-Arg(Pbf)-Glu(OtBu)-Glu(OtBu)-Tyr(tBu)-Val-Leu-Asn(Trt)-Asp(OtBu)-Ile-Gly-Val-Ile-Phe-Tyr(tBu)-Gly-Glu(OtBu)-Val-Asn(Trt)-Asp(OtBu)-Ile-Lys(Boc)-Thr(tBu)-Arg(Pbf)-Ser(tBu)-Trp(Boc)-Ser(tBu)-Tyr(tBu)-Gly-Gln(Trt)-Phe-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-Asp-Asp-Ala-Val-Tyr-Leu-Asp-Asn-Glu-Lys-Glu-Arg-Glu-Glu-Tyr-Val-Leu-Asn-Asp-Ile-Gly-Val-Ile-Phe-Tyr-Gly-Glu-Val-Asn-Asp-Ile-Lys-Thr-Arg-Ser-Trp-Ser-Tyr-Gly-Gln-Phe-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：
