Extra Details:: The major histocompatibility complex (MHC) is a cluster of genes that are important in the immune response to infections. In humans, this complex is referred to as the human leukocyte antigen (HLA) region. There are 3 major MHC class I proteins encoded by the HLA which are HLA A, HLA B and HLA C. These proteins are found on the surface of almost all nucleated somatic cells. HLA-ABC antigen is present on most nucleated cells of humans and old world monkeys. HLA Class 1 Antigen ABC is a monomorphic determinant of human Class I HLA molecules (HLA-A,B,C) associated with b2-microblogulin. It is expressed at the surface of human lymphoblastic B cells. Human Leukocyte Antigen (HLA) class I which is also known as human class I Major Histocompatibility Complex (MHC). HLA class I is encoded by three HLA alleles: HLA-A, HLA-B and HLA-C. HLA class I is a protein dimer composed of an alpha chain (Mr =44kD) and a beta chain which is also known as b2 microglobulin (Mr =12kD). The smaller beta chain bears homology with immunoglobulin molecules. The alpha chain contains four distinct regions: a cytoplasmic region located at the carboxyl terminus of the protein, followed by a transmembrane region, an immunoglobulin-like region and a peptide-binding region located at the amino terminus. This peptide binding region contains a cleft which can bind peptides consisting of 9-11 amino acid residues. HLA class 1 specifically targets the bound peptide to T cells while interacting with the T-cell receptor. HLA class 1 appears to preferentially target CD8+ T cells, whereas HLA class II preferentially targets CD4+ T cells. MaxLight™490 is a new Blue-Green photostable dye conjugate comparable to DyLight™488, Alexa Fluor™488 and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (491nm); Emission (515nm); Extinction Coefficient 73,000. Applications: Suitable for use in FLISA, Flow Cytometry, Immunohistochemistry, Immunoprecipitation. Recommended Dilution: Flow Cytometry: 1:50-1:100 Immunohistochemistry: Frozen Flow Cytometry: Use 10ul of the suggested working dilution to label 10e6 cells or 100ul whole blood. Optimal working dilutions to be determined by researcher. Recommended Positive Control: Tonsil Recommended Negative Controls: Mouse IgG2a Negative Control Recommended Secondary Reagents: F(ab')2 rabbit anti-mouse IgG HRP, F(ab')2 rabbit anti mouse IgG: RPE conjugate Fusion Partners: Spleen cells from immunized BALB/c mice were fused with cells of the mouse NS1/1-Ag4.1 myeloma cell line. 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™490 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.
