Product Overview

This rabbit polyclonal antibody targets sorcin (gene SRI) in human and rat samples and is validated for Western blot. The predicted molecular weight is 21.7 kDa, and the supplier reports an observed band at about 26 kDa.

Sorcin (SRI) is a penta-EF-hand calcium-binding protein that is abundant in heart muscle. It modulates ryanodine receptor RYR2 channels and supports calcium handling in the sarcoplasmic reticulum, so it is studied in cardiac excitation-contraction coupling.

Target Sorcin (gene SRI; UniProt P30626, human)
Host / Clonality / Isotype Rabbit / Polyclonal / Rabbit IgG
Reactivity Human, Rat
Form Lyophilized
Formulation Per vial: 0.9 mg NaCl; 0.2 mg Na2HPO4; 0.05 mg NaN3; plus stabilizers
Calculated MW 21.7 kDa
Observed MW 26 kDa
Storage As supplied: −20 °C for up to 12 months from receipt. After reconstitution: 4 °C for up to 1 month, or aliquot and keep at −20 °C for up to 6 months. Avoid repeated freeze–thaw cycles.

Validated Applications

Western blot 0.1–0.5 µg/mL (Human, Rat)

Samples with a confirmed band (WB): rat liver extract, rat brain extract and SMMC7721 cells.

Recommended loading (WB): 20–40 µg of total protein per lane.

Immunogen

Synthetic peptide from the middle region of human SR1. It differs from the mouse sequence at one residue.

Reactivity Notes

The supplier lists reactivity with human and rat. UniProt places sorcin in the cytoplasm and sarcoplasmic reticulum membrane. Tissue expression noted by UniProt (human): Detected in cardiac myocytes. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Safety

Handling: the formulation contains sodium azide as a preservative. Wear gloves, avoid contact with skin and eyes, and dispose of waste according to local regulations. For research use only; not for diagnostic or therapeutic procedures.
Q.Which applications is this antibody validated for, and at what dilution?
A.Validated applications with suggested starting dilutions: Western blot 0.1–0.5 µg/mL (Human, Rat). Optimal dilutions should be determined by each laboratory.
Q.Which species does this antibody react with?
A.Validated reactivity: Human, Rat. Other species are not listed by the supplier.
Q.Has this antibody been tested on bovine samples?
A.Reactivity with bovine samples has not been tested by the supplier. Aligning the immunogen sequence with the bovine ortholog (e.g., by BLAST) helps estimate the chance of cross-reactivity.
Q.What band size should be expected in Western blot?
A.Reported by the supplier: calculated molecular weight 21.7 kDa; observed band at about 26 kDa. A difference from the calculated size is common and can reflect post-translational modification, processing or isoform differences.
Q.What immunogen was used to raise this antibody?
A.Synthetic peptide from the middle region of human SR1. It differs from the mouse sequence at one residue.
Q.How should this antibody be stored?
A.As supplied: −20 °C for up to 12 months from receipt. After reconstitution: 4 °C for up to 1 month, or aliquot and keep at −20 °C for up to 6 months. Avoid repeated freeze–thaw cycles.
