Specificity / Sensitivity

Phospho-PKA Substrate (RRXS*/T*) (100G7E) Rabbit mAb detects peptides and proteins containing a phospho-Ser/Thr residue with arginine at the -3 and -2 positions. It is a useful tool in identifying new substrates of PKA. The antibody recognizes other -3 arginine-bearing phospho-Ser/Thr peptides, such as substrate motifs for Akt and PKC, to a lesser extent. It does not recognize the nonphosphorylated substrate motif peptides. (U.S. Patent No's.: 6,441,140; 6,982,318; 7,259,022; 7,344,714; U.S.S.N. 11,484,485; and all foreign equivalents.)

Phospho-PKA Substrate (RRXS*/T*) (100G7E) Rabbit mAb兔单抗识别包含精氨酸-3和-2位上有磷酸化丝氨酸/苏氨酸的肽段或蛋白质。它是识别PKA底物的有用工具。该抗体也可以以稍弱的强度识别包含-3位上有精氨酸的磷酸化丝氨酸/苏氨酸的肽段,如Akt和PKC的底物模体。它不能识别非磷酸化的底物模体蛋白。(美国专利号:6,441,140、6,982,318、7,259,022、7,344,714;U.S.S.N. 11,484,485;及其对应的国外部分)

Western Blotting

Western Blotting

Western blot analysis of extracts from serum-starved A431 cells, phosphorylated in vitro with PKA kinase or treated in culture with forskolin/IBMX, using Phospho-PKA Substrate (RRXS*/T*) (100G7E) Rabbit mAb. Lysis buffer: 1.0% Triton X-100 (lanes 1 and 2), 2.0% SDS (lanes 3 and 4).

对血清饥饿处理的A431细胞抽提液,使用PKA在体外磷酸化,或forskolin/IBMX培养,使用Phospho-PKA Substrate (RRXS*/T*) (100G7E) Rabbit mAb进行Western blot分析。裂解缓冲液:1.0% Triton X-100 (列1和列2), 2.0% SDS (列3和列4)。

An important class of kinases, refered to as Arg-directed kinases or AGC-family kinases, includes cAMP-dependent protein kinase (PKA), cGMP-dependent protein kinase (PKG), protein kinase C, Akt and RSK. These kinases share a substrate specificity characterized by Arg at position -3 relative to the phosphorylated Ser or Thr (1,2). Phospho-PKA substrate-specific antibodies from Cell Signaling Technology are powerful tools for investigating the regulation of phosphorylation by PKA and other Arg-directed kinases, as well as for high throughput kinase drug discovery.

精氨酸导向的激酶或AGC家族激酶是很重要的激酶,包括cAMP依赖的蛋白激酶(PKA)、cGMP依赖的蛋白激酶(PKG)、蛋白激酶C、Akt和RSK。这些激酶有相同的底物特异性,-3位上有精氨酸的丝氨酸和苏氨酸(1,2)。磷酸化PKA底物特异性抗体由Cell Signaling Technology公司研发,用于研究PKA磷酸化调节和精氨酸导向的激酶,也可以用于高通量药物发现。
