體外研究
(In Vitro)

AG957 inhibit p210bcr-abl tyrosine kinase activity. AG957 inhibits DNA synthesis as early as 2 h (60% inhibition at 20 microM). AG957 inhibits p210bcr-abl tyrosine phosphorylation in living cells by 1 h without an inhibition of total protein phosphorylation[1]. Tyrphostin AG957, a protein tyrosine kinase (PTK) inhibitor which has activity against the p210BCR/ABL kinase, on beta1 integrin function in CML progenitors[2].
AG957 (0.1-100 μM ) pretreatment results in significant inhibition of proliferation of chronic myelogenous leukemia (CML) colony-forming cells (CFC) CML CFC[2].
AG957 (25 μM) partially inhibits phosphorylation of several proteins that are BCR/ABL PTK substrates and are involved in normal integrin signaling in BCR/ABL expressing cells[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Concentration: 25 μM
Incubation Time: 24 hours
Result: Partially inhibited tyrosine phosphorylation of p210BCR/ABL, the focal adhesion protein paxillin, the p85 regulatory subunit of the PI3K and the adapter protein cbl in K562 cells.
Inhibited phosphorylation of these proteins as well as the adapter protein crkl in MBA4 cells.
體內(nèi)研究
(In Vivo)

AG957 (10 mg/kg; intratracheally 1 h before intratracheal LPS challenge) blocks c-Abl activity in the lung of mice[4].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL/6J mice[4]
Dosage: 10 mg/kg
Administration: Intratracheally 1 h before intratracheal LPS challenge
Result: LPS induced significant phosphorylation of paxillin at Y31 and Y118. Inhibition of c-Abl by AG957 attenuated LPS-induced phosphorylation of paxillin at both sites.
LPS induced significant phosphorylation of VE-cadherin in DMSO-treated mice, which was attenuated in AG957-treated mice.

以下溶解方案都請先按照 In Vitro 方式配制澄清的儲備液,再依次添加助溶劑:
——為保證實驗結(jié)果的可靠性,澄清的儲備液可以根據(jù)儲存條件,適當(dāng)保存;體內(nèi)實驗的工作液,建議您現(xiàn)用現(xiàn)配,當(dāng)天使用;
以下溶劑前顯示的百分比是指該溶劑在您配制終溶液中的體積占比;如在配制過程中出現(xiàn)沉淀、析出現(xiàn)象,可以通過加熱和/或超聲的方式助溶

  • 方案 一

    請依序添加每種溶劑: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (9.15 mM); 澄清溶液

    此方案可獲得 ≥ 2.5 mg/mL(飽和度未知)的澄清溶液。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
