  • Product overview

    Abcam’s LIF Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human LIF in serum, plasma, and cell culture supernatants.

    This assay employs an antibody specific for Human LIF coated on a 96-well plate. Standards and samples are pipetted into the wells and LIF present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human LIF antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of LIF bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

  • Notes

    Optimization may be required with urine samples.

    LIF (Leukocyte inhibitory factor) is produced by various fibroblast cell lines, antigen-stimulated alloreactive T-lymphocytes, mitogen-activated spleen cells, and Krebs and Ehrlich ascites cells. It is also produced by monocytes after cell activation. This factor inhibits the random and directed migration of polymorphonuclear (PMN) leukocytes. LIF also induces specific granule secretion by PMNs and potentiates many responses mediated by the chemotactic compound fMLP (formyl-methionyl-leucylphenylalanine).

Siento no haber contestado antes, me temo que no tengo la información de todos los productos solicitados, sin embargo, puedo proporcionarte acerca de los siguientes kits:

El kit PLTP Activity Fluorometric Assay Kit (ab65386) no es apropiado para vuestro propósito puesto que reacciona con el ortólogo murino.

Para LIF Human ELISA Kit (ab100582) no se han llevado a cabo tests de reactividad cruzada, por lo que se desconoce si reconoce la proteína murina. El anticuerpo de captura es monoclonal y el de detección policlonal. Ambas proteínas comparten un 78% de homología, por lo que algo de reactividad cruzada es de esperar.

Respecto a Complement C3 Human ELISA kit y Fibronectin Human ELISA Kit:

ab108823: se ha observado una reactividad cruzada del 0.5% con ratón y del 10% con rata.

ab108822: ninguna reactividad cruzada observada.

ab108847: no se ha observado reactividad cruzada con el ortólogo murino

ab108848: reactividad del 5% con ratón y del 20% con rata.

Con Fibronectin Human ELISA kit (with color giving dyes) (ab119524) se ha encontrado cierta reactividad cruzada de acuerdo con el colaborador que nos lo suministra.

Para ab119611 y ab119612 (uPA Human ELISA kit y uPA Receptor Human ELISA Kit) no se ha encontrado reactividad con la proteína de ratón.

No tengo de momento información acerca de ab133037 pero si sigues interesado, en cuanto la tenga te contacto de nuevo.

Si necesitáis un presupuesto o más información acerca de cualquiera de las opciones ofrecidas, por favor, no dudéis en contactarnos de nuevo y estaré encantada de poder ayudar.

This is the only kit we have for LIF. We do not know the immunogens of the two antibodies in this kit (nor have they been tested on mouse samples), therefore unable to know how much homology there is. Human and mouse LIF do share 78% homology so there is a possibility of cross reactivity but this would need to be tested.
