HER4 Protein, Rat (HEK293, His)

HER4 Protein, crucial in central nervous system development, influences neural crest cell migration and axon guidance. Additionally, it participates in mammary gland differentiation, inducing milk proteins and contributing to lactation. HER4 Protein, Rat (HEK293, His) is the recombinant rat-derived HER4 protein, expressed by HEK293 , with C-His labeled tag. The total length of HER4 Protein, Rat (HEK293, His) is 626 a.a., with molecular weight of 75-95 kDa.

ERBB4 is a protein that plays important roles in the development of the central nervous system, neural crest cell migration, and axon guidance. It is also involved in mammary gland differentiation, induction of milk proteins, and lactation.

Measured by its ability to inhibit the biological activity of Neuregulin-1-beta 1 on MCF‑7 human breast cancer cells. The ED₅₀ for this effect is 3.464 μg/mL in the presence of 10 ng/mL. Recombinant Human NRG1‑beta1, corresponding to a specific activity is 288.6836 units/mg.

75-95 kDa

Greater than 95% as determined by reducing SDS-PAGE

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

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).

Stored at -20°C for 2 years. 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.

Room temperature in continental US; may vary elsewhere.
