Calretinin antibody - 214 111C2

Calretinin is a vitamin D-dependent calcium binding protein
Mouse monoclonal purified IgG
Cat. No.: 214 111C2
Amount: 100 µg
Price: $465.00
Cat. No. 214 111C2 100 µg purified IgG, lyophilized, fluorescence-labeled with Cyanine 2.

Fluorescence labeled antibodies conjugated to Cyanine dyes are well suited for standard epi-fluorescence setups and confocal microscopy.

Cyanine 2: λex 492 nm / λem 508 nm
Sulfo-Cyanine 3: λex 554 nm / λem 568 nm
Sulfo-Cyanine 5: λex 649 nm / λem 667 nm

Cyanine 5 dyes are well suited for STORM high resolution microscopy.
Sulfo-Cyanines are highly water soluble and allow a higher labeling degree and consequently brighter conjugates.

Albumin was added for stabilization. For reconstitution add 100 µl H2O to get a 1mg/ml solution in PBS. Either add 1:1 (v/v) glycerol, then aliquot and store at -20°C until use, or store aliquots at -80°C without additives.
Reconstitute immediately upon receipt! Avoid bright light when working with the antibody to minimize photo bleeching of the fluorescent dye.

Two isoforms of the the vitamin D-dependent Ca-binding proteins have been described so far: Calretinin, also referred to as calbindin D29k, calbindin 2, CALB 2, CAL 2, and CAB 29, and calbindin D28k. These proteins are expressed in cells that have to handle a high calcium influx such as brain, bone, teeth, inner ear and others. Calbindins are believed to regulate cellular activity by suppressing or buffering intracellur calcium.
