Specification

• Source: Human cells
• Species: Human
• Preparation method: Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer with cocktail of protease inhibitors. Cell debris was removed by centrifugation and then centrifuged to clarify the lysate. The cell lysate was boiled for 5 minutes in 1 x SDS sample buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
• Lysis buffer: Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF
• Quality control Testing: 12.5% SDS-PAGE Stained with Coomassie Blue
• Recommended Usage: 1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.2. Re-dissolve the pellet using 200μL pure water and boiled for 2-5 min.3. Store it at -80°C. Recommend to aliquot the cell lysate into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.Notes:The lysate is ready to load on SDS-PAGE for Western blot application. If dissociating conditions are required, add reducing agent prior to heating.
• Stability: Samples are stable for up to twelve months from date of receipt at -80°C
• Storage Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF
• Storage Instruction: Lysate samples are stable for 12 months from date of receipt when stored at -80°C. Avoid repeated freeze-thaw cycles. Prior to SDS-PAGE fractionation, boil the lysate for 5 minutes.

Q&As

What are the implications of CD33 polymorphisms in therapeutic targeting?

Certain polymorphisms in the CD33 gene can influence its expression on the cell surface, which might affect the efficacy of CD33-targeted therapies.

What is the primary biological function of CD33 in hematopoietic cells?

CD33 is a transmembrane receptor primarily expressed on cells of myeloid lineage and is involved in modulating cellular functions, including the regulation of cellular proliferation and differentiation.

How does CD33 expression vary among different leukocyte populations?

CD33 is predominantly expressed on myeloid cells, especially on immature myeloid cells. Its expression decreases as these cells differentiate and is typically low or absent on lymphoid cells.

How has CD33 been utilized as a therapeutic target in hematological malignancies?

CD33 has been targeted for therapeutic antibodies in AML. An example is gemtuzumab ozogamicin, which targets CD33 and delivers a cytotoxic agent specifically to leukemia cells expressing CD33.

How does CD33 signaling influence myeloid cell differentiation?

While the exact signaling pathways of CD33 are still under investigation, it is believed that CD33 signaling can influence the differentiation and function of myeloid cells, potentially playing a role in immune regulation.

What role does CD33 play in acute myeloid leukemia (AML)?

CD33 is commonly expressed on the surface of AML blasts, making it a potential target for therapeutic interventions in AML.

Are there known ligands that bind specifically to CD33?

The specific ligands for CD33 are not fully characterized, but it is believed to play a role in cell-cell interactions within the immune system.
