Required for ribosomal protein bS1 (rpsA) to bind to the 30S subunit.
Recombinant Escherichia coli 30S ribosomal protein S2 (rpsB) is a recombinant protein from Escherichia coli (strain K12), expressed in E.coli, covering amino acids 2-241aa, with N-terminal GST-tagged tag, molecular weight 53.6kDa, 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.
Required for ribosomal protein bS1 (rpsA) to bind to the 30S subunit
Part of the 30S ribosomal subunit, contacts bS1 (PubMed:12068815). Some nascent polypeptide chains are able to cross-link to this protein in situ (PubMed:9716382). In collided ribosomes contacts ribosome rescue factor SmrB (PubMed:35264790)
