The human HER2 gene with the generic name ERBB2 (also known as NEU) encodes the HER2 protein or p185HER2. The HER2 protein is a membrane receptor tyrosine kinase with homology to the epidermal growth factor receptor (EGFR). The HER2 gene is a normal component present in two copies in all normal diploid cells. In a fraction of patients (15-20%) with breast cancer, the HER2 gene is amplified as

Vi är professionella HER2-sondföretag i Wuhan, främst engagerade i att tillhandahålla effektiva metoder för genetiskt test som DNA-kit, FISH-kit och FISH-sond.

Based on the results of FISH tests, patients can be qualified for treatment with antibodies that partially block HER2 receptors. This treatment causes inhibition of tumor growth signals. Determining the HER2 status in breast cancer with the FISH method allows the further progress of the disease to be predicted, the right treatment to be chosen and the response to the treatment to be foreseen.

The analysis of the HER2 status is a prerequisite for antibody (and kinase-inhibitor) based, target specific therapy in breast cancer. The diagnosis is usually done on protein level by immunohistochemistry (IH) and/or on DNA level by (Fluorescence)-in-situ-Hybridization (ISH, FISH).Strong HER2 overexpression scored 3+ (on a scale ranging from 0 over 1+, 2+ to 3+) by IH is most often based on 2020-09-21 The HER2 (Other) FISH test is used to provide HER2 amplification status to aid in determining anti-HER2 targeted therapies for various tumor types. Issues related to HER2 FISH testing, which were addressed in these guidelines, included validation, implementation, and continuous performance evaluation; FISH scoring for tumor samples with aneuploidy or genetic heterogeneity; detection of false-positive or false-negative findings; use of alternative control probes on chromosome-17 for certain subtypes of tumor samples; and handling of … 2020-07-16 HER2 treatment: the two-probe FISH pharmDx™ Kit HER2 (by Dako in 2005), the one-probe Spotlight HER2 CISH Kit (by Invitrogen in 2008), the two-probe Inform HER2 Dual SISH (by Ventana in 2011) and, most recently, the two-probe HER2 CISH pharmDx Kit™ (by Dako in 2011), which is the core topic of this present Diagnostic Profile article. FISH test results are reported as either negative or positive. FISH negative means that the levels of the HER2 gene in the cells are normal, and the tumour is HER2 negative.. FISH positive means that there is at least 4 copies of the HER2 gene in the cells, and the tumour is HER2 positive.. HER2-positive cancers are more aggressive, which means that they tend to grow and spread more quickly FISH Request AM PM AM PM Day 1 Day 2 AM PM AM PM Day 1 Day 2 AM Day 3 Dewax The Leica HER2 FISH System can deliver next day HER2 results, up to 24 hours faster than current HER2 workflow.
