  • 產(chǎn)品提供形式：
    Liquid or Lyophilized powder
    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. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
  • 復(fù)溶：
    We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
  • 儲(chǔ)存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質(zhì)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：
    Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
  • 注意事項(xiàng)：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet & COA：

靶點(diǎn)詳情

  • 功能：
    Voltage-gated calcium channel that plays a central role in calcium-dependent physiological responses essential for successful fertilization, such as sperm hyperactivation, acrosome reaction and chemotaxis towards the oocyte.
  • 基因功能參考文獻(xiàn)：
    1. explored whether steroid hormones to which human spermatozoa are exposed in the male and female genital tract influence CatSper activation via modulation of ABHD2 PMID: 28507119
    2. Electrophysiological studies showed a significant increase in Cd(2+) and manganese (Mn(2+)) currents through the CaV3.1 mutants as well as a reduction in the inhibitory effect of Cd(2+) on the Ca(2+) current. PMID: 27134080
    3. Sperm with a near absence of CatSper current failed to respond to activation of CatSper by progesterone and there was fertilization failure at IVF. PMID: 26453676
    4. The role of CATSPER1 in idiopathic asthenospermia pathogenesis: exonal SNP rs1893316 in CATSPER1 significantly correlated with idiopathic asthenospermia risk PMID: 26354096
    5. Sox5 and Sox9 cause a significant increase in transactivation of the Catsper1 promoter. PMID: 25101494
    6. Progesterone via CatSper activates the PI3K-AKT pathway required for motility and hyperactivation but not for acrosome reaction. PMID: 23623968
    7. The immediate upstream region and the first exon in the human CATSPER1 gene negatively regulate transcriptional activity. PMID: 23313885
    8. This work reports the cloning and characterization of the promoter regions in the human and murine Catsper1 genes. The immediate upstream region and the first exon in the human CATSPER1 gene negatively regulate transcriptional activity. The mouse Catsper1 promoter exhibited transcriptional activity in both orientations and displayed significant expression levels in mouse testis in vivo. PMID: 23313885
    9. CatSper is indeed the principal Ca2+ channel of human spermatozoa, and that it is strongly potentiated by progesterone. PMID: 23530196
    10. CatSper activation can elicit functionally different behaviors according to the sensitivity of the Ca(2+) store, which may be regulated by capacitation and NO from the cumulus. PMID: 23344959
    11. It was shown that odorants directly activate CatSper without involving G protein-coupled receptors and cAMP. Membrane-permeable analogues of cyclic nucleotides activated CatSper directly via an extracellular site. PMID: 22354039
    12. The decreased or abnormal expression of the CatSper1 protein may be a factor involved in the pathogenesis of idiopathic asthenozoospermia. PMID: 21404705
    13. progesterone activates the sperm-specific, pH-sensitive CatSper Ca(2+) channel PMID: 21412338
    14. human CatSper is synergistically activated by elevation of intracellular pH and extracellular progesterone PMID: 21412339
    15. Studies indicate that CATSPER channel represents a novel human male fertility factor. PMID: 20648059
    16. Potential role for CatSper in sperm motility and fertility in mouse and human. CatSper is therefore implicated as a potential target to explore the molecular mechanisms of male infertility. PMID: 14688170
    17. CATSPER1 is meiotically and post-meiotically expressed in human testis tissue. PMID: 16625279
    18. CatSper1 and CatSper2 can associate with and modulate the function of the Ca(v)3.3 channel, which might be important in the regulation of sperm function. PMID: 16740636
    19. CatSper1 may be a potential target for immunocontraception, and the antibody may be a tool to study the function of ion channels in sperm. PMID: 18976756
    20. sequence analysis of CATSPER1 in heritable forms of nonsyndromic male infertility revealed two separate insertion mutations (c.539-540insT and c.948-949insATGGC) that are predicted to lead to frameshifts and premature stop codons PMID: 19344877
