"TC Supernatant" vs. "Purified"

TC Supernatant
Hybridoma tissue-culture supernatant (5mL) generally containing 10-50 ug/mL monoclonal antibody (clone-dependent) can be a very economical choice. Supernatant is suitable for most applications including Western Blot, immunocytochemistry, immunohistochemistry etc. For applications requiring higher antibody concentration or purity (such as immunoprecipitation, microinjection, or conjugation) it is recommended that you purchase the purified form of the antibody (supplied at 1mg/mL).

Purified mAbs
Produced by in vitro bioreactor culture of hybridoma lines followed by Protein A affinity chromatography. Purified mAbs are >90% specific antibody at 1mg/mL.

Target Description:

Voltage-gated K+ channels are important determinants of neuronal membrane excitability (Pongs, 1999). Moreover, differences in K+ channel expression patterns and densities contribute to the variations in action potential waveforms and repetitive firing patterns evident in different neuronal cell types. The delayed rectifier-type (IK)channels (Kv1.5, Kv2.1, and Kv2.2) are expressed on all neuronal somata and proximal dendrites and are also found in a wide variety of non-neuronal cells types including pancreatic islets, alveolar cells and cardiac myocytes (Hwang et al., 1993; Yan et al., 2004; Michaelevski et al., 2003). Kv2.1 and Kv2.2 form distinct populations of K+ channels and these subunits are thought to be primarily responsible for IK in superior cervical ganglion cells (Blaine and Ribera, 1998; Burger and Ribera, 1996).

Immunogen:

Fusion protein amino acids 717-907 (cytoplasmic C-terminus) of rat Kv2.2 long isoform (also known as Potassium voltage-gated channel subfamily B member 2, Kcnb2 and CDRK, accession number NP_446452.2) Mouse: 94% identity (180/191 amino acids identical)
Human: 84% identity (161/191 amino acids identical)
50% identity with Kv2.1 and other Kv2 channels
100% identity with Kv2.2 short isoform for first 47 amino acids (ENRGSAPQTPPSTARPLPVTTADFPLTTPQHMSTILLEEALPQGQRP)

Cross Reactivity:

Cross-reacts with Kv2.2 short isoform. Does not cross-react with Kv2.1

Protein Name(s):

Potassium voltage-gated channel subfamily B member 2 (CDRK) (Voltage-gated potassium channel subunit Kv2.2)

Gene Name(s):

Kcnb2

Antibody Registry ID:

Purified: AB_2315866
