Kras4B Protein, Human (G13D, His)

Customer Review

Based on 1 Customer Validation

The Kras4B protein interacts specifically with GPR31, dependent on farnesylation. This binding suggests a regulatory role for Kras4B in association with GPR31, emphasizing the importance of the farnesylation process. Comprehensive exploration into the molecular details of this interaction is crucial to understand the precise mechanisms and functional implications in cellular processes or signaling pathways. Kras4B Protein, Human (G13D, His) is the recombinant human-derived KRAS protein, expressed by E. coli, with N-His labeled tag.

Biological Activity

Description

The Kras4B protein interacts specifically with GPR31, dependent on farnesylation. This binding suggests a regulatory role for Kras4B in association with GPR31, emphasizing the importance of the farnesylation process. Comprehensive exploration into the molecular details of this interaction is crucial to understand the precise mechanisms and functional implications in cellular processes or signaling pathways. Kras4B Protein, Human (G13D, His) is the recombinant human-derived KRAS protein, expressed by E. coli, with N-His labeled tag.

Background

The Kras4B protein establishes a specific interaction with GPR31, and this binding is contingent on farnesylation. This interaction underscores the potential regulatory role of Kras4B in conjunction with GPR31, suggesting a dependence on the farnesylation process. Further exploration into the molecular intricacies of this interaction is essential to unravel the precise mechanisms and functional implications associated with the interplay between Kras4B and GPR31 in cellular processes or signaling pathways.

Verified Bioactivity

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized from 0.22 μm filtered solution of 20 mM Tris, 500 mM NaCl, pH7.5 with 10% trehalose as protectant.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
