IHC staining of Purified anti-HIF1A (clone W22058A) on formalin-fixed paraffin-embedded human kidney tissue. Following antigen retrieval using Tris-EDTA (10 mM Tris, 1 mM EDTA, 0.05% Tween-20, pH 9.0), the tissue was incubated without (panel A) and with (panel B) 10 µg/mL of Purified anti-HIF1A (clone W22058A) followed by incubation with Alexa Fluor® 647 Goat anti-rat IgG (Cat. No. 405416) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801). Images were captured with a 20X objective. Scale bar: 50 µm

    Whole cell extracts (15 µg total protein) from HeLa cells untreated or treated with 200 µM CoCl2 overnight were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 0.25 µg/mL of Purified anti-HIF1A (clone W22058A) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP Goat anti-rat IgG (Cat. No. 405405). Direct-Blot™ HRP anti-GAPDH (Cat. No. 607904) was used as a loading control at a 1:50000 dilution. Western-Ready™ ECL Substrate Premium Kit (Cat. No. 426319) was used as a detection agent. Lane M: Molecular weight marker

Description

HIF1, hypoxia induced factor 1, is a heterodimeric basic helix-loop-helix transcription factor composed of HIF1α and HIF1β. Under normoxic conditions, HIF1α undergoes prolyl hydroxylation which leads to degradation of HIF1α by the proteasome. Oxygen-starvation inhibits prolyl hydroxylation and prevents proteasomal degradation of HIF1α, leading to stabilization of HIF1. HIF1α contains a nuclear localization sequence, and following nuclear translocation HIF1α binds to the core DNA sequence 5'-[AG]CGTG-3' within the hypoxia responsive element (HRE). HIF1 is a master regulator of the response to hypoxia and induces transcription of multiple genes including VEGF, glucose transporters, and proteins that aid in adaptation to hypoxic conditions. HIF1 protein is also involved in the regulation of angiogenesis, erythropoiesis, and energy metabolism.

Application

IHC-P - Quality tested
WB - Verified
Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 5.0 - 10.0 µg/mL is suggested. For western blotting, the suggested use of this reagent is 0.125 - 0.5 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This antibody (clone W22058A) is not recommended for immunocytochemistry (ICC). 

For IHC-P, antigen retrieval using Tris-EDTA pH 9.0 buffer (10mM Tris, 1mM EDTA) is recommended. Antigen retrieval with Sodium Citrate H.I.E.R. (Cat. No. 928502) is not recommended due to low signal.

Antigen Details

Structure
HIF1A is an 826 amino acid protein with a predicted molecular weight of 92.7 kD.
Distribution

Cytoplasmic in normoxia, nuclear in response to hypoxia

Function
Transcription factor, oxygen sensor
Interaction
Forms a dimer with Hif1β. Prolylation conducted by prolyl hydroxylase (PHD) and HIF prolyl hydroxylase (HPH), and subsequent degradation is mediated by von Hippel-Lindau tumor suppressor (VHL).
