Crosstide is a synthetic peptide substrate for Akt.1 It corresponds to the amino acid sequence of glycogen synthase kinase 3 (GSK3) that surrounds the serine residue phosphorylated by p90 ribosomal S6 kinase 1 (RSK1) or p70 ribosomal S6 kinase (p70S6K). Crosstide has been used in the study of Akt activity.1,2 It is also a substrate for serum/glucocorticoid-regulated kinase family member 3 (SGK3).3

Kinase experiment: | After serum deprivation for 24 h, cells are incubated with digoxigenin-labeled sham protein or digoxigenin-labeled RV39 at an MOI of 1.0 for 10 min. Cell homogenates are immunoprecipitated with mouse anti-digoxigenin antibody and precipitates incubated with Crosstide and [γ-32P]ATP. Crosstide is a glycogen synthase kinase α/β fusion protein sequence (GRPRTSSFAEG) which is a substrate for Akt. Samples are processed for autoradiography and immunoblotting using rabbit anti-phospho-Tyr416 Src, mouse anti-Src (clone GD11), rabbit anti-phospho-Ser473, or rabbit anti-Akt. |

工作液浓度： mg/ml；
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。
