Purified splenic NK cells from the LEW rat strain.
MaxLight(TM)550 is a new Yellow-Green photostable dye conjugate comparable to Alexa Fluor(TM)546, 555, DyLight(TM)549 , Cy3(TM), TRITC and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (550nm), Emission (575nm), Extinction Coefficient 150,000. Natural killer (NK) cells are lymphocytes that mediate cytotoxicity and secrete cytokines after immune stimulation. Several genes of the C-type lectin superfamily, including the rodent NKRP1 family of glycoproteins, are expressed by NK cells and may be involved in the regulation of NK cell function. The KLRB1 protein contains an extracellular domain with several motifs characteristic of C-type lectins, a transmembrane domain, and a cytoplasmic domain. The KLRB1 protein, NKR-P1A or D161, is classified as a type II membrane protein because it has an external C terminus.[1] NKR-P1A, the receptor encoded by the KLRB1 gene, recognizes Lectin Like Transcript-1 (LLT1) as a functional ligand. Human CD161 is a homodimeric disulfide-linked type II membrane bound glycoprotein found mainly on NK cells. CD161 has been implicated in the regulation of NK cell mediated cytotoxicity. Applications: Suitable for use in Flow Cytometry, Immunohistochemistry and Immunoprecipitation. Other applications not tested. Recommended Dilutions: Immunohistochemistry: Frozen sections Optimal dilutions to be determined by the researcher. Hybridoma: X63-Ag8-653 myeloma cells with spleen cells from Balb/c mice. Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight(TM)550 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Note: Applications are based on unconjugated antibody.
