Flow Cytometry, Live Cell Protocol for Directly Conjugated Antibodies

A. Solutions and Reagents

NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.

  1. 1X Phosphate Buffered Saline (PBS): To prepare 1 L 1X PBS: add 100 ml 10X PBS (#12528) to 900 ml water, mix.
  2. Antibody Dilution Buffer: Purchase ready-to-use Flow Cytometry Antibody Dilution Buffer (#13616), or prepare a 0.5% BSA PBS buffer by dissolving 0.5 g Bovine Serum Albumin (BSA) (#9998) in 100 ml 1X PBS. Store at 4°C.

NOTE: When including fluorescent cellular dyes in your experiment (including viability dyes, DNA dyes, etc.), please refer to the dye product page for the recommended protocol. Visit www.cellsignal.com for a full listing of cellular dyes validated for use in flow cytometry.

B. Immunostaining

NOTE: Count cells using a hemocytometer or alternative method.

NOTE: If using whole blood, lyse red blood cells and wash by centrifugation prior to Immunostaining.

NOTE: Optimal centrifugation conditions will vary depending upon cell type and reagent volume. Generally, 150-300g for 1-5 minutes will be sufficient to pellet the cells.

  1. Aliquot desired number of cells into tubes or wells. (Generally, 5x105 to 1x106 cells per assay.)
  2. Pellet cells by centrifugation and remove supernatant.
  3. Resuspend cells in 100 µl of diluted primary antibody, prepared in Antibody Dilution Buffer at a recommended dilution or as determined via titration.
  4. Incubate for 30 min to 1 hr on ice. Protect from light.
  5. Wash by centrifugation in Antibody Dilution Buffer. Discard supernatant. Repeat.
  6. Resuspend cells in 200-500 µl of Antibody Dilution Buffer and analyze on flow cytometer.

Specificity / Sensitivity

KLRG1 (2F1) Hamster mAb (APC Conjugate) recognizes endogenous levels of total KLRG1 protein. This antibody detects an epitope within the extracellular domain.

Species Reactivity:

Mouse

Source / Purification

This monoclonal antibody was purified from tissue culture supernatant via affinity chromatography. The purified antibody was conjugated under optimal conditions, with unreacted dye removed from the preparation.

Background

Killer cell lectin-like receptor G1 (KLRG1), also known as mast cell function associated antigen (MAFA), is an inhibitory type II transmembrane lectin-like receptor (1,2). This glycoprotein is expressed on a subset of natural killer (NK) and T cells (3,4). KLRG1 is considered a marker of T cell senescence (5,6). Studies have shown that KLRG1 is upregulated by MHC Class I molecule expression and these interactions can be mediated by lectin-like class I-specific Ly49 inhibitory receptors (1,3). KLRG1 triggering interferes with the activating TCR pathway and inhibits cytotoxicity (2). Specifically, KLRG1 binds to cadherin family ligands (E-, N-, and R-), inhibiting NK cell cytotoxicity (7). The effect that KLRG1 has on NK cell differentiation, maturation, homeostasis, and activation, make it an important target when studying innate immune regulation and chronic viral infections (8).
The 2F1 antibody is widely used to detect KLRG1 on mouse cells (1).
