Y-box-binding protein 1 (UniProt: P67809; also known as YB-1, CCAAT-binding transcription factor I subunit A (CBF-A), DNA-binding protein B, Enhancer factor I subunit A, EFI-A, Nuclease-sensitive element-binding protein 1, Y-box transcription factor) is encoded by the YBX1 (also known as NSEP1, YB1) gene (Gene ID: 4904) in human. Y-box-binding protein 1 (YB-1) belongs to the cold shock domain (CSD) protein family, which is characterized by a highly conserved nucleic acid-binding domain. YB-1′s structure includes the CSD at the N-terminus and a diverse C-terminal domain that contains both alternating basic and acidic regions. This structure facilitates its role in binding to both DNA and RNA, enabling a wide range of functions. YB-1 is a multifunctional protein that plays significant roles in various cellular processes including regulation of transcription, translation of mRNAs, DNA repair, and stress response. It acts as a transcription factor that can both activate and repress genes. In translation, YB-1 binds to mRNA and can affect its stability and translation efficiency, often in response to cellular stress. YB-1 is ubiquitously expressed across various tissues but shows higher expression levels in lung, colon, and breast tissues. Its overexpression has been observed in many cancers, including breast, ovarian, lung, and prostate cancers, and is often linked with aggressive tumor growth, increased metastasis, and resistance to treatment. Additionally, YB-1 has been implicated in other pathological conditions such as inflammation and fibrosis.
ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

Biochem/physiol Actions
Clone 1G7 is a ZooMAb® rabbit recombinant monoclonal antibody that detects YB1. It targets an epitope within 23 amino acids from the N-terminal region.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
