Replace your flint on a butane lighter. The flint is the piece of equipment that creates the spark. It's tiny black cylinder about a quarter inch long. To replace the flint, remove the metal surrounding the flame and the spark wheel. You'll have to twist it out of position.
Intrinsic factor (IF), also known as gastric intrinsic factor (GIF), is a glycoprotein produced by the parietal cells of the stomach.It is necessary for the absorption of vitamin B12 (cobalamin) later on in the small intestine. In humans, the gastric intrinsic factor protein is encoded by the GIF gene.t is necessary for the absorption of vitamin B12 (cobalamin) later on in the small intestine.

This test detects intrinsic factor antibody (IF antibody) circulating in blood. Intrinsic factor is a protein produced by a type of specialized cells that line the stomach wall known as parietal cells. During digestion, stomach acids release vitamin B12 from food and bind to intrinsic factor to form a complex.wo types of IF antibodies can be tested by the laboratory: 1  Intrinsic factor blocking antibody (type 1), which is more specific for pernicious anemia and is the one that is usually tested. 2  Intrinsic factor binding antibody (type 2), which interferes with the uptake of the vitamin B12-instrinsic factor complex.
