REACH authorisation
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 Lamin B Receptor (LBR) also known as L. B. R. L B R or lamin B is a protein located in the inner nuclear membrane. This protein has a molecular mass of approximately 70 kDa. It acts as a receptor for lamin proteins specifically lamin B. The LBR mediates the attachment of heterochromatin and lamins to the inner nuclear membrane playing a structural role in the maintenance of nuclear architecture. It is widely expressed in various tissues notably in cells involved in rapidly proliferating tissues.
Biological function summary
The LBR protein serves several critical functions beyond its mechanical duties. It participates in the regulation of chromatin organization and gene expression owing to its interaction with chromatin-related proteins. LBR is part of the nuclear envelope lattice and forms complexes with lamin proteins and heterochromatin. This association supports its role in anchoring chromatin at the nuclear periphery modulating processes such as DNA replication and transcription.
Pathways
The LBR plays pivotal roles in nuclear envelope assembly and chromatin organization. It holds significance in the cholesterol biosynthesis pathway where it metabolizes sterol intermediates to cholesterol. This function relates LBR to other proteins including lamin A/C which collaborate in maintaining nuclear shape and function. Together they orchestrate various cellular processes important for cell cycle progression and differentiation.
Alterations in LBR function have links to conditions such as Pelger-Huët anomaly and Greenberg skeletal dysplasia. Pelger-Huët anomaly manifests as a benign hematologic condition with defective nuclear shape in neutrophils while Greenberg dysplasia is characterized by skeletal abnormalities. In these contexts LBR connects to lamin B and other nuclear envelope proteins that contribute to the pathophysiological features observed in these disorders.
