The actual band is not consistent with the expectation.
Western blotting is a method for detecting a certain protein in a complex sample based on the specific binding of antigen and antibody. Different proteins can be divided into bands based on different mobility rates. The mobility is affected by many factors, which may cause the observed band size to be inconsistent with the expected size. The common factors include: 1. Post-translational modifications: For example, modifications such as glycosylation, phosphorylation, methylation, and acetylation will increase the molecular weight of the protein. 2. Splicing variants: Different expression patterns of various mRNA splicing bodies may produce proteins of different sizes. 3. Post-translational cleavage: Many proteins are first synthesized into precursor proteins and then cleaved to form active forms, such as COL1A1. 4. Relative charge: the composition of amino acids (the proportion of charged amino acids and uncharged amino acids). 5. Formation of multimers: For example, in protein dimer, strong interactions between proteins can cause the bands to be larger. However, the use of reducing conditions can usually avoid the formation of multimers. If a protein in a sample has different modified forms at the same time, multiple bands may be detected on the membrane. |

| background | CALB2 (Calbindin 2) is a Protein Coding gene. Diseases associated with CALB2 include Adenofibroma and Adenomatoid Tumor. GO annotations related to this gene include calcium ion binding. An important paralog of this gene is CALB1.This gene encodes an intracellular calcium-binding protein belonging to the troponin C superfamily. Members of this protein family have six EF-hand domains which bind calcium. This protein plays a role in diverse cellular functions, including message targeting and intracellular calcium buffering. It also functions as a modulator of neuronal excitability, and is a diagnostic marker for some human diseases, including Hirschsprung disease and some cancers. Alternative splicing results in multiple transcript variants. |
