关于本试剂盒
The Human LTF (Lactoferrin) ELISA quantitates LTF in serum and plasma.
原理方法
The Human Lactoferrin (LTF) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the concentration of Lactoferrin (LTF) in biological samples. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are added into these wells and bind to the immobilized (capture) antibody.
The sandwich complex is formed by the addition of a second (HRP-linked) detection antibody specific to Lactoferrin (LTF). Excess reagents are washed from the plate.
A substrate solution is added that reacts with the enzyme-antibody-target complex to produce a measurable signal. The enzyme-substrate reaction is terminated by the addition of stop solution. The intensity of the signal, measured spectrophotometrically at 450 ± 2 nm, is directly proportional to the concentration of Lactoferrin (LTF) present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

靶标信息
Lactoferrin (LF) is an iron binding glycoprotein. LF consists of a single polypeptide chain (approximately 80 kDa) folded into two structurally homologous lobes, each of which can reversibly bind one ferric ion (Fe3+). LF is found in external fluids, including milk and mucosal secretions, and is a prominent component of secondary granuals of neutrophils. The protein demonstrates a broad spectrum of properties, including regulation of iron homeostasis, host defense against a broad range of microbial infections, anti-inflammatory activity, regulation of cellular growth and differentiation and protection against cancer development and metastasis. LTF acts as a major first line defense against microbial infections, partly due to its ability to efficiently bind to and hence remove Fe3+ from the environment, but studies have also shown that LTF possesses bactericidal properties and proteolytic activity, capable of cleaving arginine-rich sequences within microbial proteins. Three isoforms of LTF have been identified: LTF-alpha, LTF-beta and LTF-gamma and receptors for LTF are expressed in the gastrointestinal tract, by macrophages, lymphocytes, neutrophils and platelets and also by some bacteria.
