Product Specification

Alternative Name:	HECT, UBA and WWE domain-containing protein 1, Upstream regulatory element-binding protein 1, Mcl-1 ubiquitin ligase E3, ARF-binding protein 1, Large structure of UREB1, Homologous to E6AP carboxyl terminus homologous protein 9, E3-histone

Host:	Rabbit

Immunogen:	Recombinant N-terminal fragment (aa 1367-1552) of mouse Huwe1 protein (accession number: Q7TMY8).

UniProt ID:	Q7TMY8

Source:	Purified from rabbit serum.

Species reactivity:	Human, Mouse, Rat

Applications:	WB

Recommended Dilutions/Conditions:	Western Blot (an initial dilution of 1:100 is recommended due to the dilute nature of the immunoaffinity purified antibody) Note: Huwe1 is a large (485kDa), labile protein that is susceptible to fragmentation upon freeze thaw and upon heating. DO NOT heat lysate/protein samples when preparing for SDS-PAGE. Western blotting conditions appropriate for the transfer of large proteins must be used to ensure good transfer of Huwe1 protein to immunoblotting membranes. For example use BSN transfer buffer 48mM TRIS, p9.2, 39mM glycine with 10% MeOH and 0.0375% SDS. Suggested dilutions/conditions may not be available for all applications. Optimal conditions must be determined individually for each application.

Purity Detail:	Antigenic protein fragment affinity purified.

Formulation:	Liquid. In 100mM TRIS, pH 7.0, containing 100mM glycine and 0.02% sodium azide.

Use/Stability:	Stable for at least 6 months after receipt when stored at 4°C.

Handling:	Do not freeze.

Shipping:	Blue Ice Not Frozen

Short Term Storage:	+4°C

Long Term Storage:	+4°C

Scientific Background:	Ubiquitin E3 ligase that ubiquitinylates a range of target proteins involved in various cellular processes including MCL1 (apoptosis regulation), p53 (tumor suppression), core histones H1, H2A, H2B, H3 and H4 (chromatin modification), MYCN (neural differentiation regulation) and CDC6 (DNA damage response). Has been shown to be overexpressed in many human tumors and to play a role in spermatogenesis and neurogenesis.

Regulatory Status:	RUO - Research Use Only
