  • 产品描述:

    The human HIF-1α ELISA Kit allows for the in vitro quantitative determination of HIF-1α concentrations in serum, plasma, or tissue homogenates. This kit exclusively recognizes human HIF-1α. HIF-1α is a nuclear transcription factor that has been identified as a biomarker of the hypoxia microenvironment in most types of solid tumors. Under hypoxia, HIF-1α becomes relatively stable and binds to HIF-1β to form the active HIF-1 heterodimer. Many studies have reported that HIF-1α is detected in the majority of solid tumors including breast cancer, gastric cancer, and cervical cancer, and is linked to cell proliferation, metabolism, immune responses, apoptosis, genomic instability, vascularization, invasion, and metastasis of tumor cells. HIF-1α is also associated with chemo-/radioresistance. Pharmacological HIF-1α suppression is thus required for reversing chemo-/radioresistance in tumors.

    The detection mechanism of this kit is based on the Sandwich-ELISA technique. HIF-1α in the sample is bound to the capture antibody immobilized on the microtiter plate and then sandwiched with a Biotin-labeled HIF-1α antibody. The solution color develops into blue after the ordinal addition of HRP-avidin and TMB. The color development is terminated after adding the stop solution, and the color turns from blue to yellow. The color intensity is positively correlated with HIF-1α content in the sample. The kit has been quality-controlled with high sensitivity, strong specificity, good linearity, high precision, high recovery, and high lot-to-lot consistency.

 常见问题解答
Q:

我想问你关于血清HIF-1的ELISA试剂盒检测范围。 我们的研究需要测量血清HIF-1的水平。但在我们的研究对象中,预计HIF-1低于CUSABIO试剂盒的最低检测值62.5 pg/mL 因此,您的HIF-1&alpha试剂盒可能检测不了我的样本,请问您有其他更好的解决方案吗?

A:
关于试剂盒CSB-E12112h的参数,请参考网上发布的使用说明。如果浓度在试剂盒的检测范围内,就可以正常检测到。实际上,62.5 pg/mL-4000 pg/mL的检测范围意味着在这个范围内的结果更准确。但是如果你的样品浓度较低,那么确实有可能出现无法检测到的结果。 如果您的样品确实低于试剂盒的检测范围,很抱歉我们目前暂无更好的解决方案。

靶点详情

  • 功能:
    Functions as a master transcriptional regulator of the adaptive response to hypoxia. Under hypoxic conditions, activates the transcription of over 40 genes, including erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, HILPDA, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia. Plays an essential role in embryonic vascularization, tumor angiogenesis and pathophysiology of ischemic disease. Heterodimerizes with ARNT; heterodimer binds to core DNA sequence 5'-TACGTG-3' within the hypoxia response element (HRE) of target gene promoters. Activation requires recruitment of transcriptional coactivators such as CREBBP and EP300. Activity is enhanced by interaction with NCOA1 and/or NCOA2. Interaction with redox regulatory protein APEX1 seems to activate CTAD and potentiates activation by NCOA1 and CREBBP. Involved in the axonal distribution and transport of mitochondria in neurons during hypoxia.; (Microbial infection) Upon infection by human coronavirus SARS-CoV-2, is required for induction of glycolysis in monocytes and the consequent proinflammatory state. In monocytes, induces expression of ACE2 and cytokines such as IL1B, TNF, IL6, and interferons. Promotes human coronavirus SARS-CoV-2 replication and monocyte inflammatory response.
