|0.2 μm filtered solution in PBS with 5% trehalose|
|Produced in rabbits immunized with purified, recombinant Human SPEG / APEG-1 (rh SPEG / APEG-1; Catalog#12472-H08E; Q15772-4; Met 1-Glu 113). SPEG / APEG-1 specific IgG was purified by Human SPEG / APEG-1 affinity chromatography.|
|Human SPEG / APEG-1|
ELISA: 0.1-0.2 μg/mL
This antibody can be used at 0.1-0.2 μg/mL with the appropriate secondary reagents to detect Human SPEG. The detection limit for Human SPEG is approximately 0.00975 ng/well.
|This antibody can be stored at 2℃-8℃ for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20℃ to -70℃. Preservative-Free.|
Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.
Striated muscle preferentially expressed protein kinase, also known as aortic preferentially expressed protein 1, APEG-1, SPEG and KIAA1297, is a protein which belongs to the protein kinase superfamily and CAMK Ser/Thr protein kinase family. SPEG / APEG-1 contains two fibronectin type-III domains, nine Ig-like (immunoglobulin-like) domains, two protein kinase domains. Isoform 1 of SPEG is preferentially expressed in striated muscle. Non-kinase form such as isoform 3 of SPEG is predominantly expressed in the aorta. Isoform 3 of SPEG appears to be expressed only in highly differentiated ASMC in normal vessel walls and down-regulated in dedifferentiated ASMC. Isoform 3 of SPEG may have a role in regulating the growth and differentiation of arterial smooth muscle cells. Isoform 3 of SPEG is quickly down-regulated in response to vascular injury, when ASMC cells change from a quiescent to a proliferative phenotype.
