Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, E-P=Peptide ELISA (DELFIA),

Specificity / Sensitivity

Phospho-(Ser/Thr) PKD Substrates Antibody detects peptides and proteins containing a phospho-Ser/Thr residue with arginine at the -3 position and leucine at the -5 position, prefering proline at the -1 position within the motif. The antibody may cross-react with some peptides and proteins containing an arginine residue at -3 position and a hydrophobic or basic residue at the -5 position. (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-(Ser/Thr) PKD Substrates Antibody识别包含-3位上有精氨酸和-5位上有亮氨酸的磷酸化丝氨酸/苏氨酸残基的肽段或蛋白,最好在-1位上还有脯氨酸。此抗体可能与包含-3位精氨酸和-5位疏水或碱性氨基酸的肽段或蛋白有交叉反应。(美国专利号:6,441,140、6,982,318、7,259,022、7,344,714;U.S.S.N. 11,484,485;及所有国外相应专利)

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phospho-PKD substrate peptide. Antibodies are purified by protein A and peptide affinity chromatography.

Protein kinase D1 (PKD1), also called PKCμ, is one member of the protein kinase D family. PKD members are serine/threonine protein kinases implicated in very diverse cellular functions including cell growth and survival, Golgi organization and immune response (1). The information about the natural substrates of PKD is limited (2,3). The enzyme recognizes and phosphorylates the following consensus sequence: LXRXXS/T. Phospho-(Ser/Thr) PKD Substrate Antibody recognizes phosphorylated PKD substrates at their consensus motif, providing a powerful new tool for PKD target discovery and characterization as well as HTS drug screening for potential kinase regulators.

Protein kinase D1 (PKD1),也称为PKCμ,是蛋白激酶D家族的一员。PKD成员是丝氨酸/苏氨酸蛋白激酶,涉及多种细胞内功能包括细胞生长和存活、高尔基体组装和免疫反应等(1)。目前对PKD自然底物的信息了解有限(2,3)。该酶识别并磷酸化一致序列:LXRXXS/T。Phospho-(Ser/Thr) PKD Substrate Antibody识别含共同基序磷酸化的PKD,为PKD目标物的发现和鉴定提供了强大的工具,也为潜在激酶调节者的高通量药物筛选提供了强大的工具。
