產品提供形式：

Liquid or Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
貨期：

3-7 business days
注意事項：

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

功能：

Transcriptional coactivator that specifically associates with either POU2F1/OCT1 or POU2F2/OCT2. It boosts the POU2F1/OCT1 mediated promoter activity and to a lesser extent, that of POU2F2/OCT2. It has no intrinsic DNA-binding activity. It recognizes the POU domains of POU2F1/OCT1 and POU2F2/OCT2. It is essential for the response of B-cells to antigens and required for the formation of germinal centers. Regulates IL6 expression in B cells as POU2F2/OCT2 coactivator.
基因功能參考文獻：
1. The number of follicular B2 lymphocytes and expression of the B-cell-specific transcriptional coactivator OcaB increase with age in spleen and in intra-abdominal epididymal white adipose tissue (eWAT), concomitantly with higher circulating levels of IgG and impaired glucose homeostasis. PMID: 29496744
2. These findings demonstrate for the first time that functional polymorphism in the 3'-UTR of POU2AF1 is associated with susceptibility, and that single-nucleotide polymorphisms interaction with hsa-miR-633 affects gene expression and increases the risk of lymphoma. PMID: 28345816
3. Oct2 and Bob1 are very reliable in determining B cell lineage in the absence of expression of other pan-B cell markers PMID: 27319306
4. these findings suggest a novel function of POU2AF1 as a potential regulator of host defense genes in the human airway epithelium. PMID: 26927796
5. It has been identified as a new disease susceptibility gene among Japanese. Though different from Europeans, it is indicated that a B lymphocyte differentiation route shares a common disease developing process. [Review] PMID: 24005100
6. Two significant susceptibility loci, TNFSF15 (rs4979462) and POU2AF1 (rs4938534) (combined odds ratio [OR] = 1.56, p = 2.84 x 10(-14) for rs4979462. PMID: 23000144
7. genetic polymorphism is associated with common variable immunodeficiency PMID: 21905497
8. Data show that Igh 3' enhancer-bound OCA-B and promoter-bound TFII-I mediate promoter-enhancer interactions, in both cis and trans, that are important for Igh transcription. PMID: 21549311
9. On multivariate analysis, co-expression of OCT-2/BOB.1 remained predictive for achievement of complete remission and increased risk of relapse. PMID: 20141429
10. BOB.1 may be helpful marker in the differential diagnosis of classical Hodgkin's lymphoma and primary mediastinal B-cell lymphoma PMID: 20102401
11. The expression of the octamer cofactor gene OBF-1 (Bob1/OCA-B) is sufficient to override the silencing effects of the B29 silencer, indicating that OBF-1 plays a critical role in B cell-specific B29 promoter expression. PMID: 11907094
12. enhances transcriptional potential of Oct1 PMID: 12727885
13. OCA-B sustains expression of the immunoglobulin-secreting program when T lymphoma and plasmacytoma lines are fused, requiring Oct-2 coregulator for its function. PMID: 14662861
14. POU2AF1 was observed to be differentially expressed in the cells of patients with chronic lymphocytic leukemia. PMID: 15672409
15. Alteration of the BOB1 locus does not correlate with its suppressed expression in Hodgkin lymphoma. PMID: 15796964
16. Novel germ cell markers BOB1 were significantly upregulated in seminoma specimens, compared to normal testes. PMID: 17785371
17. Oct-2 and its cofactor Bob-1 have an important function in mediating the IgH enhancer-bcl-2 promoter region interactions PMID: 18695675
