Description

Mouse Monoclonal Antibody

Description: The monoclonal antibody 14.27 reacts with rat CD38, also known as ADP-ribosyl cyclase. CD38 is a type II transmembrane glycoprotein that is an ectoenzyme that catalyzes the synthesis and hydrolysis of cyclic adenosine diphosphate ribose (cADPR) and nicotinic acid adenine dinucleotide phosphate (NAADP). cADPR and NAADP are secondary messengers involved in calcium mobilization. CD38 can also act as a receptor for CD31 or agonist monoclonal antibodies. CD38 is expressed by leukocytes, early hematopoietic precursor cells, epithelial cells, astrocytes, some muscle cells, kidney cells, and thyroid cells. CD38 plays a role in the production of pro-inflammatory cytokines, proliferation, cell activation, cell migration, cell adhesion, and protection from apoptosis. Applications Reported: This 14.27 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 14.27 antibody has been tested by flow cytometric analysis of rat splenocytes. This can be used at less than or equal to 0.25 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. eFluor® 660 is a replacement for Alexa Fluor® 647. eFluor® 660 emits at 659 nm and is excited with the red laser (633 nm).

CD38 is a multifunctional ectoenzyme and type II transmembrane glycoprotein involved in various cellular processes. It catalyzes the conversion of NAD into secondary messengers such as nicotinic acid adenine dinucleotide phosphate (NAADP) and cyclic ADP-ribose (cADPR). CD38 plays a crucial role in B cell development, with expression levels fluctuating from high in immature cells to low in intermediate ones, and back to high in mature B cells. It is also present in a variety of tissues and hematopoietic cells, including T cells, NK cells, and monocytes, and is used to phenotype leukemias and monitor HIV-1 progression. The CD34+CD38- population is considered to define the most pluripotent hematopoietic stem cells. In addition to its surface expression, CD38 has been identified in the nucleus, where it may regulate calcium levels. It functions as a multi-catalytic ectoenzyme, serving roles as an ADP-ribosyl cyclase, cyclic ADP-ribose hydrolase, and possibly NAD+ glycohydrolase, or as a cell surface receptor. CD38 is involved in the activation, proliferation, and differentiation of mature lymphocytes and mediates apoptosis of myeloid and lymphoid progenitor cells. It also participates in cell adhesion, signal transduction, and calcium signaling. Antibodies to CD38 are valuable for subtyping lymphomas and leukemias, detecting plasma cells (such as in myelomas), and marking activated B and T cells. CD38 is expressed at high levels in the pancreas, liver, kidney, malignant lymphoma, and neuroblastoma. Dysfunctions in CD38 are associated with diseases like chronic lymphocytic leukemia and Richter's Syndrome.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

Can the eFluor Organic fluorochromes be used for intracellular staining?

Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).

Is the eFluor 660 fluorochrome compatible with Anti-Cy5/Alexa Fluor 647 beads?

Yes, in-house studies have demonstrated that the eFluor 660 fluorochrome is recognized by Anti-Cy5/Alexa Fluor 647 beads. Side by side studies with Alexa Fluor 647 versus eFluor 660 conjugated antibodies have demonstrated comparable results.

What buffers are compatible with the eFluor Organic fluorochromes and eVolve QDots?

The eFluor Organic fluorochromes and eVolve QDots can be used with flow staining buffers containing PBS and protein.

What is the difference between eFluor Organic Dyes and eVolve Qdots?

The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
