hsa-miR-24-3p antagomirs are chemically-modified oligonucleotides that hybridize with mature miRNAs. The miRNA antagomirs have 2 phosphorothioates at the 5' end, 4 phosphorothioates at the 3' end, 1 cholesterol group at the 3' end, and full-length nucleotide 2'-methoxy modification. The miRNA antagomirs strongly compete with mature miRNAs to prevent the complementary pairing of miRNAs and their target genes, thereby inhibiting miRNAs from functioning. Stability of miRNA antagomirs appears to be significantly higher than miRNA inhibitors, they exhibits enhanced cellular uptake, stability and regulatory activity in vivo.

Description

hsa-miR-24-3p antagomirs are chemically-modified oligonucleotides that hybridize with mature miRNAs.

In Vitro

1. miRNA的配制

1.1 miRNA产品呈透明或半透明的干膜状附着在管壁上,使用前将试管瞬时离心,以确保 miRNA 位于试管底部。使用不含核酸酶的水重新配制 miRNA,得到20 μM的母液。

对于5 nmol miRNA:加入250 μL 无核酸酶水,涡旋振荡数次溶解。

对于20 nmol miRNA:加入1000 μL 无核酸酶水,涡旋振荡数次溶解。

1.2 (可选) 将 miRNA 分装到一个或多个管子中以减少冻融的次数(<5)。

1.3 将配制好的母液在-20℃或-80℃条件下保存。

2. 准备细胞

2.1 预先接种细胞,待达到合适的细胞密度时进行细胞转染。转染前细胞活力影响转染结果。

3. 转染

3.1 制备转染混合物A和B

注:对于 miRNA mimics,我们推荐的工作浓度为 50nM。miRNA 产品最佳工作浓度因不同的细胞类型及研究目的而异,这取决于miRNA、细胞系和选择的分析方法。为了确定最佳结果的浓度,应该使用不同的浓度进行优化实验。优化后的浓度范围为 10~200nM。

6孔板的每孔:A: 245 μL无血清培养基+ 5 μL miRNA;B: 240 μL无血清培养基+ 10 μL HY-K2017 siRNA/miRNA Transfection Reagent

12孔板的每孔:A: 97.5 μL无血清培养基+ 2.5 μL miRNA;B: 95 μL无血清培养基+ 5 μL HY-K2017 siRNA/miRNA Transfection Reagent

24孔板的每孔:A: 48.75 μL无血清培养基+ 1.25 μL miRNA;B: 47.5 μL无血清培养基+ 2.5 μL HY-K2017 siRNA/miRNA Transfection Reagent

96孔板的每孔:A: 24.75 μL无血清培养基+ 0.25 μL miRNA;B: 24.5 μL无血清培养基+ 0.5 μL HY-K2017 siRNA/miRNA Transfection Reagent

如果使用其他品牌的转染试剂,需要根据具体情况调整转染试剂加入的量。

3.2 将稀释好的 A 和 B 轻轻混合。室温孵育15-20分钟。

3.3 从细胞中去除培养基,用 PBS 洗涤。

3.4 向细胞中添加 miRNA-转染试剂混合物。

6孔板的每孔:加入1500 μL不含血清的新鲜培养基,然后加入500 μL的转染混合物 (A+B),混匀。

12孔板的每孔:加入800 μL不含血清的新鲜培养基,然后加入200 μL的转染混合物 (A+B),混匀。

24孔板的每孔:加入400 μL不含血清的新鲜培养基,然后加入100 μL的转染混合物 (A+B),混匀。

96孔板的每孔:加入50 μL不含血清的新鲜培养基,然后加入50 μL的转染混合物 (A+B),混匀。

3.5 在37℃孵育细胞1-3天。然后分析转染细胞。可在转染约 6 小时后将无双抗和血清培养基更换为正常含血清和双抗培养基。

注:转染时的培养基中不要加入抗生素,否则会降低细胞转染的效率,甚至导致细胞死亡。

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.
