  • Function

    Low affinity receptor for N-formyl-methionyl peptides, which are powerful neutrophils chemotactic factors. Binding of FMLP to the receptor causes activation of neutrophils. This response is mediated via a G-protein that activates a phosphatidylinositol-calcium second messenger system. The activation of LXA4R could result in an anti-inflammatory outcome counteracting the actions of proinflammatory signals such as LTB4 (leukotriene B4).
  • Tissue specificity

    Expressed abundantly in the lung and neutrophils. Also found in the spleen and testis.
  • Sequence similarities

    Belongs to the G-protein coupled receptor 1 family.
  • Cellular localization

    Cell membrane.

  • FACS analysis of BOSC23 cells using ab26316. BOSC23 cells were transiently transfected with with an expression vector containing either FPRL1/RFP (red curve) or a control transfectant (black curve). Binding of ab26316 was detected using a PE-conjugated secondary antibody.

  • ab26316 staining of FPRL1/RFP in CHO cells using 1µg/106 cells. CHO cells were transiently transfected with an expession vector encoding FPRL1/RFP and binding of ab26316 was visualized using a FITC-conjugated secondary antibody (green). Actin filaments are labelled with Alexa Fluor-55 Phalloidin (red). Cell nuclei are stained with DAPI (blue).

  • ab26316, staining FPRL1/RFP (green) in and sub-acutely injured equine superficial digital flexor tendons by Immunohistochemistry (Frozen sections).

    After warming cryosections at room temperature for 30 minutes, sections were rehydrated in 1% PBS-Tween 20 (PBS-T) and blocked in PBS containing 5% normal goat serum for 1 hour at room temperature. Sections were incubated with the primary antibody (1/100 in PBS + 5% normal goat serum) for 2 hours. An AlexaFluor®488-conjugated goat anti-mouse IgG was used as the secondary antibody (1/300).

Thank you for your enquiry and your interest in our products.

The antibody ab26316 recognizes the extracellular part of the receptor. We tested this in FACS on transiently transfected cells. Some customers tested the antibody and its ability to block the receptor:

Here are some useful and specific publications you may wish to take a look at:

Thank you for contacting us.

Antibodies are sometimes pre-adsorbed. This means they have been adsorbed with other proteins, or serum from various species, etc, to eliminate any antibody that may cross-react. The resulting purified antibody should be very pure and specific and any cross reactivity should be significantly reduced.

As shown on the datasheet, the primary antibody ab26316 is a Mouse IgG1. Therefore I confirm that ab99605 is compatible with ab26316.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
