Annexin V-FITC Apoptosis Detection Kit
Zenith's Annexin V-FITC Apoptosis Detection kit allows for fluorescent detection of annexin V bound to apoptotic cells and quantitative determination by flow cytometry. The process needs only a 15-minute incubation procedure.
Annexin V has a high affinity in a Ca2+-dependent manner to negatively charged phospholipid phophatidylserine, which is found on the outer cell membrane early during apoptosis. The Annexin V-FITC kit employs FITC conjugated Annexin V in concert with propidium iodide (PI).
As the cell membrane becomes increasingly permeable during the later stage of apoptosis, propidium iodide can readily move across the cell membrane and bind to DNA. This combination allows the differentiation among 3 populations of cells in two-color flow cytometry:
- Normal cells: Annexin V negative and PI negative
- Early apoptotic cells: Annexin V positive and PI negative
- Necrotic cells or late apoptotic cells: Annexin V positive and PI positive.
Alternatively, the cell can be examined with a fluorescence microscope equipped with FITC and rhodamine filter sets.
Comments:
- Detects apoptosis earlier in the process than DNA-based assays such as TUNEL.
- Rapid labeling of cells. Cell staining takes only 10 minutes.
- No cell fixation or processing required, reducing the detection time and allowing the cells to be used for further study.
- Propidium iodide secondary dye is included with the kit to differentiate apoptotic cells from viable and necrotic cells.

Rapid urase test
Helicobacter pylori is a bacterium found in the gastrointestinal tract of up to 60 percent or two-thirds of the world’s population. Most individuals infected with it will not develop symptoms or be affected by it. However, H. pylori can cause several gastrointestinal disorders, including ulcers, stomach cancer and chronic gastritis (inflammation of the stomach). The bacterium releases enzymes that allow it to invade the lining of the stomach and the first part of the small intestine, called the duodenum. These areas are then more vulnerable to damage from the stomach’s digestive acid and this, in turn, may cause chronic inflammation in the stomach (gastritis) or duodenum (duodenitis), and sometimes ulcer formation. The actual source of H. pylori infection is unknown but is thought to include swimming in, or drinking, fecal-contaminated water, or eating uncooked vegetables. Proper precautions include washing the hands (15-30 seconds with antibacterial soap), drinking clean water from a reliable source and eating only well-cooked foods.
 |  |
Symptoms of H. pylori infection include the following:
Upper abdominal pain (often described as a burning or gnawing pain)
Nausea and/or vomiting
Decreased appetite
Dark stools (blood passed from the stomach through the intestines produces dark stools)
H. pylori can be diagnosed in a number of ways, including blood tests that look for antibodies made by the body in response to the infection. Other tests include stool studies that detect proteins produced by the bacterium, and a breath test. The breath test involves swallowing a substance that is degraded by the bacteria and can then be detected by sampling a patient’s breath.
Another more invasive method is endoscopy, where a specialized, flexible tube is placed through the mouth, past the esophagus and into the stomach. The tube contains a camera and light that allow the physician to view the esophagus, stomach and duodenum and take biopsies for H. pylori testing.
H. pylori is treated with a combination of at least two antibiotics and a proton-pump inhibitor for 7 to 14 days. The combination of medications has about a 90 percent cure rate when the patient takes all the medication as prescribed.
H. pylori produce large amounts of the enzyme urease. Although the primary function of urease is to allow H. pylori to utilize urea as a nitrogen source, the breakdown of urea also produces high local concentrations of ammonia. When a tissue specimen from a patient is assayed by the HelicoRapt test, the elevated pH level produced by the presence and activity of urease is indicated by a color change in the test paper.
Procedure :
 | On the front side of the slide record the patient's information. We recommend two slides per patient for confirmation of the result. |
 | The total procedure is delineated on the back side of the slide. |
 | Open the test slide. |
 | Transfer the biopsy sample onto the test paper using a sterile needle. |
 |
Re-seal the slide. |
 | Press the top cover over the test paper to squeeze the fluid out of the biopsy sample. |
 |
Monitor the test slide over the course of an hour. Observe any color change through the window on the back of the test slide. |

Real-time PCR based test
Traditionally, scientists and clinicians have used assays that involve growing cultures to screen samples for the presence of pathogenic microorganisms. Today, culture- based methods for pathogen detection are rapidly being replaced by faster and more specific Real Time PCR assays that discriminate between microorganisms based on a signal from specific nucleic acid sequences.
We have developed high quality Real Time PCR assays for various human pathogens and molecular diseases. The kits contain both extraction reagents and real time PCR reagents with positive controls. They are designed with the broadest possible detection profile from detailed sequence alignments of representative members of the strain/subtype.
Components of core kit are:
- Specific primers and probe in 20X formulation.
- 2X PCR mastermix.
- Reagents for cDNA conversion (if applicable)
- Linearized plasmid standard (10M copies per mL) for 10 standard curves
Components of total kit are:
- Core kit.
- Nucleic acid extraction reagent.
