Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.
Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

The Eph receptor B4 also known as EphB4 or HTK is a protein belonging to the Ephrin receptor subfamily of receptor tyrosine kinases. The receptor has a molecular weight of about 120 kDa. EphB4 typically interacts with its binding partner ephrin-B2 facilitating bidirectional signaling. These complexes reside in the cell membrane and are mainly found in vascular endothelial cells and various tissues including the heart lungs and skin. Notably this receptor plays a role in cellular processes like cell migration and adhesion.
The Eph receptor B4 is a significant regulator of angiogenesis and vascular development. It forms a critical component of a signaling complex that also includes ephrin-B2. During embryonic development EphB4's interaction with ephrin-B2 guides the proper formation and organization of blood vessels. In adult organisms it remains active in maintaining vascular homeostasis. Additionally this receptor impacts neuronal development and repair through modulating axon guidance and synaptic plasticity.
EphB4 engages in various cellular signaling cascades. It features prominently within pathways governing angiogenesis and cell adhesion. EphB4 acts as a central player in the VEGF signaling pathway modulating endothelial cell behavior. The protein’s pathways frequently intersect with other proteins such as FAK and Src influencing cell motility and morphology. Furthermore in the ephrin receptor pathway it cross-talks with other Eph receptors like EphA4 assisting in diverse biological functions.
Abnormal Eph receptor B4 activity associates with several pathological conditions. Dysregulation often links to cancer due to its role in neovascularization and tumor progression. Overexpression of EphB4 in tumors like breast and colorectal cancer suggests a contribution to malignancy by supporting angiogenesis and tumor growth. In vascular disorders impaired EphB4-ephrin-B2 signaling may lead to defects in blood vessel formation. Additionally alterations in this receptor are observed in neurological diseases such as Alzheimer's where EphB4 interacts with tau protein-modifying vascular and neuronal deficiencies.
