Comments:

Background: PIASy1 functions as an E3-type small ubiquitin-like modifier (SUMO) ligase, stabilizing the interaction between UBE2I and the substrate, and as a SUMO-tethering factor. This protein plays a crucial role in transcriptional coregulation of various cellular pathways, including the STAT pathway, the p53 pathway, the wnt pathway and the steroid hormone signaling pathway. PIASy1 is involved in gene silencing, and promotes PARK7 sumoylation.

Application Details

Application Notes: The suggested dilution is: ELISA~~1:1,000 Western blotting~~1:100~500 Immunohistochemistry~~1:50~100

Concentration: 0.25 mg/ml

Purification: Purified

Buffer: Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein G column, eluted with high and low pH buffers and neutralized immediately, followed by dialysis against PBS.

Storage: Maintain refrigerated at 2-8 deg C for up to 6 months. For long term storage store at -20 deg C in small aliquots to prevent freeze-thaw cycles

Images

The anti-PIASy polyclonal antibody (ABIN388061) is used in Western blot to detect PIASy in HL-60 cell lysate.

Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry. clinical relevance has not been evaluated. BC = breast carcinoma. HC = hepatocarcinoma.
