APPLICATION

Application Note

For ELISA: Use at a concentration of 0.5 - 1 μg/ml. For ELISA, the detection limit for human recombinant HB-EGF is ~0.03 ng/well. For Neut: Use at an assay dependent dilution. For WB: Use at a concentration of 1 - 2 μg/ml. For WB, the detection limit for human recombinant HB-EGF is ~0.5 ng/lane under non-reducing and reducing conditions. Predicted molecular weight: 23 kDa. Optimal dilutions/concentrations should be determined by the researcher.

Calculated MW

23 kDa. ( Note )

Positive Control

Vascular smooth muscle cells.

Specificity/Sensitivity

This antibody will neutralize the biological activity of recombinant human HB EGF. It will not neutralize the biological activity of EGF, TGFalpha, or amphiregulin.

Buffer

Lyophilized from 5% Trehalose, PBS, in 100μg BSA Reconstitute the lyophilized antibody with sterile PBS, pH 7.4, or sterile 20 mM Tris-saline (20 mM Tris containing 0.15 M NaCl), pH 7.4, to yield a final concentration of 0.25 mg/ml.

Storage

Store as concentrated solution. Centrifuge briefly prior to opening vial. For short-term storage (1-2 weeks), store at 4ºC. For long-term storage, aliquot and store at -20ºC or below. Avoid multiple freeze-thaw cycles.

Cellular Localization

Type I membrane protein. Mature HB-EGF is released into the extracellular space and probably binds to a receptor.

Background

Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a 22kDa O-glycosylated protein that is a potent mitogen and chemoattractant for vascular smooth muscle cells, fibroblasts and epithelial cells but not endothelial cells. The natural protein has an apparent molecular mass of 19-23 kDa and exists in multiple forms as a result of heterogeneous O-glycosylation and/or Nterminal truncation. HB-EGF is synthesized as a membrane-anchored precursor(proHB-EGF) that is proteolytically cleaved to release the soluble mature growth factor. The two forms are active as juxtacrine and paracrine/autocrine growth factors respectively.HB-EGF activates two EGF receptor subtypes, HER1/ErbB1 and HER4 and binds to heparan sulfate proteoglycan.
