Research AreasDevelopmental Biology

Function

Has an essential role in conjugative DNA transfer (CDT), the unidirectional transfer of ssDNA plasmid from a donor to a recipient cell. It is the central mechanism by which antibiotic resistance and virulence factors are propagated in bacterial populations. Part of the relaxosome, which facilitates a site- and strand-specific cut in the origin of transfer by TraI, at the nic site.

Biological Context

Subcellular Location: Cytoplasm, nucleoid

Product Specifications

Recombinant Escherichia coli Integration host factor subunit alpha (ihfA) is a recombinant protein from Escherichia coli (strain K12), expressed in E.coli, covering amino acids 2-99aa, with N-terminal 10xHis-tagged and C-terminal Myc-tagged tag, molecular weight 18.7kDa, purity Greater than 90% as determined by SDS-PAGE.. Suitable for ELISA and Western Blot applications.

SDS-PAGE: Single band at expected molecular weight confirming purity.

ELISA: Suitable as coating antigen or detection standard.

Western Blot: Compatible with standard Western Blot protocols.

Protein Interaction: Validated for SPR (Surface Plasmon Resonance) and BLI (Bio-Layer Interferometry) studies.

Shipping: Shipped at ambient temperature. Lyophilized protein is stable during transit.

Storage: Store lyophilized protein at -20°C to -80°C. Reconstituted protein should be aliquoted and stored at -80°C. Avoid repeated freeze-thaw cycles.

Shelf Life: 12 months from date of receipt when stored as recommended.

Shipping Time: Orders placed before 2 PM EST ship same day. International orders typically deliver within 5-10 business days.

Protein Biology

Function

Has an essential role in conjugative DNA transfer (CDT), the unidirectional transfer of ssDNA plasmid from a donor to a recipient cell. It is the central mechanism by which antibiotic resistance and virulence factors are propagated in bacterial populations. Part of the relaxosome, which facilitates a site- and strand-specific cut in the origin of transfer by TraI, at the nic site. Relaxosome formation requires binding of IHF and TraY to the oriT region, which then facilitates binding of TraI (PubMed:7499339, PubMed:7499340)

Subcellular Location

Cytoplasm, nucleoid

Subunit

Heterodimer of an alpha and a beta chain. Part of the relaxosome, a complex composed of plasmid-encoded TraI, TraM, TraY and host-encoded IHF bound to the F plasmid origin of transfer (oriT) (PubMed:7499339, PubMed:7499340)

Frequently Asked Questions

How do I order or inquire about this product?

Fill out the Online Inquiry form with your required quantity and specifications. You can also email sales@biocrestsci.com. Our team typically responds within 4 business hours with a quote and availability confirmation.

What is the shipping and delivery time?

Orders placed before 2 PM EST ship the same day. Domestic (US) delivery typically takes 2-3 business days. International orders deliver within 5-10 business days. All products are shipped at ambient temperature with appropriate packaging to ensure stability.

How should I store this recombinant protein?

Lyophilized proteins should be stored at -20°C to -80°C upon receipt. After reconstitution, aliquot and store at -80°C. Avoid repeated freeze-thaw cycles. Shelf life is 12 months from date of receipt when stored as recommended.

What quality controls are performed on your products?

Each product undergoes SDS-PAGE purity analysis (typically >85-95%), endotoxin testing, and bioactivity validation. Products are validated for ELISA, Western Blot, and SPR/BLI applications as specified on this product page. A Certificate of Analysis (CoA) is available upon request.
