Buffer:

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Research Areas:

Epigenetics and Nuclear Signaling

Function:

Single-stranded DNA-specific cytidine deaminase. Involved in somatic hypermutation (SHM), gene conversion, and class-switch recombination (CSR) in B-lymphocytes by deaminating C to U during transcription of Ig-variable (V) and Ig-switch (S) region DNA. Required for several crucial steps of B-cell terminal differentiation necessary for efficient antibody responses

Involvement in disease:

Immunodeficiency with hyper-IgM 2 (HIGM2)

Relevance:

Single-stranded DNA-specific cytidine deaminase. Involved in somatic hypermutation , gene conversion, and class-switch recombination in B-lymphocytes by deaminating C to U during transcription of Ig-variable and Ig-switch region DNA. Required for several crucial steps of B-cell terminal differentiation necessary for efficient antibody responses . May also play a role in the epigenetic regulation of gene expression by participating in DNA demethylation.

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
