Helicobacter Pylori IgG ELISA Kit

Full Name: Helicobacter Pylori IgG ELISA Kit
Reactivity: Human
Sample Type: Serum, Plasma
Sensitivity: 1.16 U/ml

BACKGROUND

Helicobacter pylori (H. pylori) is a gram negative bacteria which is usually associated with stomach cancers (especially non-cardia gastric cancer). It can enter the body and attack the lining of the stomach, the acid used in the stomach to digest food functions to protect the lining from the bacteria.

Prolonged infection can lead to the development of ulcers, excess bleeding and prevention of food moving through the digestive tract. H. pylori are helix-shaped bacteria which are also called curved rods, having a diameter of 0.5μm and length 3μm.

INTENDED USE

Human helicobacter pylori IgG ELISA kit is designed for detecting in-vitro levels of human IgG antibodies against helicobacter pylori (helicobacter pylori-IgG) in serum and plasma. This assay has a minimum analytical sensitivity limit of 1.16 U/ml.

CONTENT

All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

  • Helicobacter pylori antigen coated microtiter strips.
  • Enzyme Conjugate.
  • TMB Substrate.
  • Sample Diluent.
  • Washing Buffer (10x).
  • Stop Solution.
  • Calibrator B (Cut-Off Standard).
  • Calibrator D (Positive Control).
  • Calibrator C (Weak Positive Control).
  • Calibrator A (Negative Control).

SENSITIVITY

The minimum detection sensitivity level of human IgG antibodies to helicobacter pylori (helicobacter pylori-IgG) using current helicobacter pylori IgG ELISA kit was 1.16 U/ml. The dynamic range for this assay is 1.0 – 150.0 U/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
