CD45.1 is an alloantigen of CD45, expressed by Ly5.1 bearing mouse strains (e.g., RIII, SJL/J, STS/A, DA). CD45, a member of the protein tyrosine phosphatase (PTP) family, is a 180-240 kD glycoprotein expressed on all hematopoietic cells except mature erythrocytes and platelets. There are multiple isoforms in mice that play key roles in TCR and BCR signal transduction. These isoforms are very specific to the activation and maturation states of the cell as well as specific cell types. The primary ligands for CD45 are galectin-1, CD2, CD3, CD4, TCR, CD22, and Thy-1.

Q: What is a “StarBright panel”?
A: A StarBright panel is a multiplex panel that includes at least one StarBright conjugate.
Q: Will my StarBright panel be provided as a cocktail?
A: StarBright products purchased as part of a panel or StarBright Basic Panel will be provided in individual vials. To order premade cocktails, please contact our Custom Solutions Team.
Q: Are StarBright GMP/ASR products available?
A: StarBright ASR and GMP products are coming soon.
Q: Are StarBright custom products available?
A: Yes, please contact our Custom Solutions Team.
Q: Will StarBright isotype controls be offered?
A: We are not planning to offer StarBright isotype controls at this time. Fluorescence Minus One (FMO) controls should be used to define gating boundaries.
Q: What amount of a StarBright conjugate should I use?
A: Antibody conjugates should be titrated for optimal performance in each application. To directly compare performance with a traditional or polymer-conjugated antibody, we recommend using the same volume of each product for analysis. Due to differences in the quantification of product mass, StarBright Dyes are prepared in equivalent volumes.
Q: Why shouldn’t I compare the mass (μg) of a StarBright conjugate to a traditional or polymer conjugate?
A: For StarBright conjugates, the reported mass refers to the mass of the dye component. For traditional conjugates, the reported mass refers to the mass of the antibody component. This is because traditional conjugates have multiple dye molecules attached to one antibody, while StarBright conjugates have multiple antibodies attached to a single StarBright Dye.
