Chlorotoxin (trifluoroacetate salt)
(Synonyms: CTX; TM-601) 目录号 : GC92127Chlorotoxin (trifluoroacetate salt)是从蝎L. quinquestriatus的毒液中分离出来的肽。
Sample solution is provided at 25 µL, 10mM.
Chlorotoxin is a peptide originally isolated from the venom of the scorpion L. quinquestriatus.1,2 It inhibits chloride currents in rat colonic enterocyte plasma membrane preparations when used at a concentration of 594 nM.1 Chlorotoxin also binds to, but does not inhibit, matrix metalloproteinase-2 (MMP-2; IC50s = 0.71 and >30 ?M, respectively), as well as neuropilin-1 (NRP-1; IC50 = 0.78 ?M) in cell-free assays.3 It induces paralysis in crayfish (P. clarkii) but is not cytotoxic to human U87MG glioma, MCF-7 breast cancer, PC3 prostate cancer, and A549 lung cancer cells.1,2 Administration of chimeric antigen receptor (CAR) T cells expressing CAR with chlorotoxin as the targeting domain increase survival and decrease tumor volume in an orthotopic patient-derived xenograft (PDX) mouse model of glioblastoma.4 Liposomes containing chlorotoxin and encapsulating doxorubicin decrease tumor volume in a U87 glioma mouse xenograft model.5 Fluorescently labeled chlorotoxin has been used for tumor imaging in vivo.6

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
