- Extra Details:
- MaxLight™550 is a new Yellow-Green photostable dye conjugate comparable to Alexa Fluor™546, 555, DyLight™549 , Cy3™, TRITC and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (550nm); Emission (575nm); Extinction Coefficient 150,000. Recognizes a protein of 205kD-220kD, identified as CD45RA. CD45RA is isoforms of the human leukocyte common antigen (CD45). Human CD45 contains three exons which encode peptide segments designated A, B and C, respectively. The differential splicing of the exons generates at least five isoforms, ABC, AB, BC, B and O. This antibody reacts with ABC and BC isoforms. CD45RA is expressed on 40-50% of peripheral CD4+ T-cells, 50% of peripheral CD8+ T-cells, B-cells, and leukemic B-cell lines. T-cells expressing CD45RA are naive or virgin T-cells. T-cells expressing CD45RO are memory T-cells. CD45RA and CD45RO define complementary, predominantly non-overlapping populations of resting peripheral T-cells. This MAb is useful in study on the subpopulation of CD4+ or CD8+ T-cells. It can especially be used to differentiate T-cell lymphomas (CD45RO +ve) from B cell lymphomas (CD45RA +ve). Applications: Suitable for use in Immunofluorescence, Flow Cytometry, FLISA, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested. Recommended Dilution: Flow Cytometry: 0.5-1ug/million cells Immunofluorescence: 1-2ug/ml Western Blot: 0.5-1ug/ml Immunoprecipitation: 1-2ug/500ug protein lysate Immunohistochemistry (Frozen & Formalin-fixed): 0.5-1ug/ml for 30 minutes at RT (Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes) Optimal dilution for a specific application should be determined. Positive Control: Daudi, Raji, IM9, and human lymphocytes. Human lymph nodes and tonsils. Storage and Stability: Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C 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™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.
